NCP5030MTTXGEVB NCP5030 High PowerLighting Evaluation Board User's ManualOverviewThe NCP5030 is a fixed frequency PWM buck −boost converter optimized for constant current applications such as driving high −powered white LED. The buck −boost is implemented in an H −bridge topology and has an adaptive architecture where it operates in one of three modes: boost,buck −boost, or buck depending on the input and load condition. This device has been designed with high −efficiency for use in portable applications and is capable of driving up to 1.2 A pulse current and 900mA continuous current into a high power LED for camera flash,flashlight, torch and similar applications. To protect the device cycle by cycle current limiting and a thermal shutdown circuit have been incorporated as well as outputOVP (Over −V oltage Protection). The high switching frequency allows the use of a low value 4.7 m H inductor and ceramic capacitors. The NCP5030 is in a low profile and efficient thermally enhanced 3 x 4 mm DFN package.NCP5030 High Power Lighting Evaluation BoardThis evaluation board demonstrates the overall NCP5030capabilities and offers very easy current programming. The output current is fully configurable via the usage of 4external resistors and corresponding jumper headers. The NCP5030 lighting evaluation board schematic is depicted in Figure2.Figure 1.

超特克HV9918DB1高流LED驱动示例板说明书

Supertex inc.HV9918DB1High Current LED Driver DemoboardThe HV9918DB1 demoboard is a high current LED driver designedto drive one or two LEDs at 700mA from a 9.0 - 16VDC input. Thedemoboard uses Supertex’s HV9918 hysteretic buck LED driver IC.The HV9918DB1 includes digital control of PWM dimming, which allows the user to dim the LEDs using an external, TTL-compatible square wave source applied between DIM and GND . In this case, the PWM dimming frequency and duty ratio are set by the external square wave source.The demoboard is protected against short circuit and open LEDconditions. It also includes thermal derating of the LED current us-ing an external NTC resistor to prevent over-heating.The bottom of the HV9918DB1 is an exposed copper plane (con-nected to the input ground) which can be connected to a 1” square heatsink (eg: 374324B00035G from Aavid Thermalloy) to allow for operation in higher ambient temperatures without tripping the HV9918’s built-in over temperature protection.General DescriptionInput Connection: Connect the input DC voltage between VIN andGND terminals.Output Connection:Connect the LED(s) between LED+ (anode of LED string) and LED- (cathode of LED string) ter-minals.PWM Dimming Connection:1. If no PWM dimming is required, short PWMD and VDD terminals.2. If dimming using an external PWM dimming source, connect the PWM source between the PWMD and GNDterminals.NTC Thermistor Connection:1. If no thermal derating is required, the NTC terminalcan be left open.2. If thermal derating of the LED current is required, the NTC thermistor can be connected between NTCand GND terminals as shown.ConnectionsSilk ScreenOperation of the BoardThe HV9918DB1 uses Supertex’s HV9918 hysteretic buck LED driver IC to control the LED current. Since the regula-tion method controls both the peak and the valley current in the inductor, the demoboard has excellent line and load regulation.The LED current can be controlled in by PWM dimming. PWM dimming can be achieved in one of two ways:1. Analog control of PWM dimming where a 0-2V sourcecan be applied between NTC and GND terminals (the NTC terminal can also be used for thermal derating of the LED current as explained in the next section).2. Direct control of PWM dimming by applying a TTL com-patible square wave source between PWMD and GND terminals.Analog Control of PWM Dimming / Thermal De-ratingAnalog Control of PWM dimming can be accomplished by applying a 0 – 2.0V DC voltage between NTC and GND (the DC voltage must have a 500μA source/sink capability). In this case, PWMD is connected to VDD and the LEDs are dimmed at 1.0kHz (as set by the capacitor at the RAMP pin of the IC). The duty cycle of the LED current can be adjusted by varying the external voltage at NTC (0V = 0% LED cur-rent and 2.0V = 100% LED current).The same NTC terminal can instead be used to de-rate the LED current based on the LED temperature, if desired. This would reduce the LED current as the LED temperature rises and prevents over-heating of the LED. An NTC resistor can be used to sense the temperature of the LED and this resis-tor can be connected between the NTC and GND terminals of the HV9918DB1. The demoboard is designed to operate with a 100k NTC thermistor which has a B-constant of 4250 (eg: NCP18WF104 from Murata). With this NTC thermistor, the LED current will start dropping at 85ºC and will reach about 350mA at 125ºC.Thermal derating in the HV9918DB1 uses the analog control of PWM dimming function to limit the LED current when the LED temperature rises. During normal operating mode (con-stant LED current; no PWM dimming), the LED current will be PWM dimmed at 1.0kHz. During PWM dimming mode, the thermal derating function limits the maximum PWM dim-ming duty cycle so that the LED current does not exceed the maximum allowable current determined by the thermal derating circuit.Direct Control of PWM DimmingIn the direct control method, the PWM dimming of the LEDs is achieved by driving the PWMD terminal using an external square wave source. In this case, PWM dimming frequency and duty cycle are set by the external source.In this mode, if the thermal derating function is not desired, NTC terminal should be left open. In this case, the recom-mended PWM dimming frequency can be anything up to 10kHz.If thermal derating is desired, then the NTC thermistor should be connected between the NTC and GND terminals. In this case, the PWM dimming frequency should be greater than 1.2kHz.Fig. 1. Normal Operation – Drain Voltage and LED CurrentFig. 2. PWM Dimming WaveformFig. 3.

Thermal Derating of the LED CurrentII Normal inductor current waveformII 0Note:The increase in the LED current at 9.0V input and 6.7V output can be explained by the fact that when the dif-ference between the input and output voltages is very small, the rising inductor current waveform becomes more exponential rather than linear (the falling edge of the inductor current remains linear because the output voltage is high). This causes the average inductor (and therefore LED) current to increase even though the up-per and lower bounds are still the sameHV9918DB1 Schematic DiagramHV9918DB1 WaveformsSupertex inc. does not recommend the use of its products in life support applications, and will not knowingly sell them for use in such applications unless it receives an adequate “product liability indemnification insurance agreement.” Supertex inc. does not assume responsibility for use of devices described, and limits its liability to the replacement of the devices determined defective due to workmanship.

The EV kit is set up for boost and buck-boost configurations and operates from a 6V to 18V DC supply voltage. The string-forward voltage can vary from 3V to 36V. The EV kit is optimized for 0.8A and a series of 8 LEDs in a string. Other configurations may require changes to component values.Analog Dimming Control (REFI)When J2 is installed across pins 1-2, the LED current is set at the maximum current. The REFI pin is connected to VCC and in this case, the LED current is given by the following equation:LED 220mVI R14=In the case of the EV kit, I LED is set to 0.88A.When J2 is installed across pins 2-3, the REFI pin is con -nected to the voltage-divider of R1 and R2, which sets the REFI voltage. If V REFI < 1.2V, then V REFI sets the LED current level.()REFI LEDV 0.2V I 5R14−=×Alternatively, the analog dimming can be controlled by removing the shunt on J2 and applying a voltage between 0 and 5.5V on the REFI test point on the EV kit. REFI voltages above 1.3V are limited to an equivalent of 1.3V inside the IC.Pulse-Dimming Input (PWMDIM)The EV kit demonstrates the PWM dimming feature of the buck controller using either an external PWM signal, or a DC voltage at the DIM pin.Analog-to-PWM dimming: Install a shunt across J1 (1-2). Adjust the potentiometer R18 to set a DC voltage on the PWMDIM pin. The PWM dimming duty cycle is set by the voltage at PWMDIM between 0.2V (0% duty) and 3V (100% duty). Alternatively, drive the PWMDIM testpoint with an external DC source. PWMDIM voltages above 3V set the dimming duty cycle to 100%.Direct PWM dimming: Leave J1 open and connect a PWM signal to the PWMDIM testpoint. Vary the duty cycle to increase or decrease the intensity of the HB LED string. The PWMDIM input of the device has a 2V (max) rising threshold and a 0.8V (min) falling threshold and is com -patible with 3.3V and 5V logic-level signals. Uninstall C2 to achieve fast PWMDIM rise and fall edges at the IC pin.Table 1.

The dimming frequency is internally set at 200Hz.2-3Connects the PWMDIM pin to ground to disable the analog dimming function and keep the IC off.OpenConnect an external function generator to drive the PWMDIM pin with a signal from 0 to 3.3V or higher. PWMDIM pulse width should be at least above one switching period.Recommended PWMDIM frequency range is from 200Hz to 2kHz for visible LEDs. IR LEDs can operate at lower frequencies where flicker is not visible.J21-2*Connects VCC to the REFI pin. LED current is at the maximum value of 0.88A in this configuration.2-3Connects the REFI pin of the device to VCC through a voltage divider formed by R1 and R2.Adjusting R2 allows programming the LED current from 0 to 0.88A for REFI levels from 0.2V to 1.3V. For REFI voltages above 1.3V, the LED current is limited at 0.88A.OpenConnect an external voltage source to set the LED current from 0 to 0.88A for REFI levels from 0.2V to 1.3V. For REFI voltages above 1.3V, the LED current is limited at 0.88A.J71-2*Connects the IN pin to the same input supply as the boost power stage through a 10Ω filter resistor.OpenConnect an external supply voltage greater than 4.7V to J7 pin 2 to bias the IC IN pin.Evaluates: MAX25611A/MAX25611B MAX25611 Evaluation Kit2.2MHz OperationThe EV kit can be used to evaluate 2.2MHz operation. To test the 2.2MHz application:●Change the IC to MAX25611B (provided).●Change L2 to 2.2µH.●Change C9 to 0.22µF. R6 remains at 50Ω.●Output capacitance can be reduced to 1x 4.7µF. Notethat short pulse widths at low frequencies benefit from having higher total output capacitance to counter leak-age currents that discharge the output voltage before the next pulse.●Change other components as required (e.g., MOSFET,FET current sense R9, LED current sense R14). High-Beam/Low-Beam ApplicationThe EV kit can be used to evaluate high-beam/low-beam switching applications. Connect the low-beam LED string across LED+ and HB_LED+, and the high-beam LED string across HB_LED+ and GND. Use a function genera-tor or a DC source to drive the HIGHBEAM_OFF pad to 5V or GND to disabled or enable the high-beam LEDs. Slew rate control of the driving signal, or adjustment of R19 and C17 values can be used to control the transi-tion of the Q3 shunting FET to minimize surge currents through the low-beam LEDs.Latch CircuitThe latch circuit proves HB+LED+ short-to-battery protec-tion by disabling the shunt FET gate. This prevents the shunt FET from shorting out the battery. The latch is reset by removing power to recycle VCC.Voltage Regulator ConfigurationThe EV kit can be reconfigured as a voltage regulator using R27 and R28 as the voltage feedback resistor divider, after removing R14.()()REFIOUTV0.2R27R28V5R27−+=×Setting V REFI = 1.2V selects a large feedback signal for better accuracy and noise immunity. For simplicity, select R27 to match the programmed regulation voltage across ISENSEP and ISENSEN. For example, with V REFI = 1.2V, V(ISENSEP - ISENSEN) = 200mV, and R27 should be 200Ω. This makes 1mV per Ω or 1mA down the resis-tor string, minimizing the error due to ISENSEN leakage current. The calculation for R28 is then simplified to (VOUT - 0.2) x 1000.The following components should also be changed:●Power stage components (Q1, L2, D1, R9 and outputcapacitance) as required for the application (voltage, current rating, etc).●COMP components (R6, C9, C16) to match the appli-cation requirements.●Remove C14, R17, and Q2.#Denotes RoHS compliance.PART TYPEMAX25611EVKIT#EV KitOrdering InformationEvaluates: MAX25611A/MAX25611B MAX25611 Evaluation KitMAX25611 EV Kit Bill of MaterialsITEM REF_DES DNI/DNP QTY MFG PART #MANUFACTURER VALUE DESCRIPTION1C1, C19—2GRM32ER72A225KA35;CGA6N3X7R2A225K230;CC1210KKX7R0BB225MURATA;TDK;YAGEO2.2UFCAPACITOR;

The MAX16141 is a diode controller and protection device that protects systems against fault conditions such as reverse current, overcurrent, input overvoltage/undervoltage, short circuit and over temperature. The MAX16141 EV kit’s undervoltage and overvoltage thresholds are configured to 8.6V and 36.2V, respectively.The MAX16141 EV kit comes with the MAX16141ATE+ (16-TQFN) installed and is configured to operate normally between 8.6V and 36.2V. Under normal operation, the output follows the input. The output will shut down (0V) when the input is risen above 36.2V (i.e., 37V or higher), or drop below 8.6V (i.e., 7V or lower). The output will also shut down when the load at the output goes above 5A, or in an event of a short circuit at the output.SHDNThe MAX16141 EV kit provides a jumper (JU1) to enable or disable the MAX16141. Refer to Table 1 for JU1 jumper settings.SLEEPThe MAX16141 EV kit provides a jumper (JU2) to pullup the active-low sleep mode input of the MAX16141. Refer to Table 2 for JU2 jumper settings.GATE SnubberFor applications that require slower gate rise time than what is achieved using a resistor from GRC to GND, an external resistor and capacitor (snubber) network can be added from GATE to GND. However, the recommended value is 1k Ω resistor in series with a 10nF cap.The MAX16141 EV Kit provides a jumper (JU3) to add or remove the snubber at the power MOSFET gates. Refer to Table 3 for jumper settings.Overvoltage ProtectionThe MAX16141 EV kit shuts down the output when the input voltage exceeds the upper input voltage limit set by resistors R11 and R9 between the TERM and OVSET pins of the MAX16141. Refer to the equation below to set the overvoltage limit for the MAX16141 EV kit.R11 = ((VOV_TH x R9)/VTH) - (R9 + 700Ω)where,VOV_TH is the desired overvoltage threshold.R9 = 10kΩV TH = 0.5V (typ) threshold for OVSET and 700Ω is the TERM switch typical resistance.Undervoltage ProtectionThe MAX16141 EV kit shuts down the output when the input voltage drops below the lower input voltage limit set by resistors R10 and R8 between the TERM and UVSET pins of the MAX16141. Refer to the equation below to set the undervoltage limit for the MAX16141 EV kit.R10 = ((V UV_TH x R8)/V TH ) - (R8 + 700Ω)where,V UV_TH is the desired undervoltage threshold.R8 = 10kΩV TH = 0.5V (typ) threshold for UVSET and 700Ω is the TERM switch typical resistance.Table 2.

Refer to the equation below to set the overcurrent limit for the MAX16141 EV kit.RSENSE = V(RS-OUT)/IOCTHwhere,RSENSE is the sense resistor between RS and OUT in Ω,V(RS-OUT) is the overcurrent threshold in V (refer to the IC data sheet for the proper value)IOCTH is the desired overcurrent threshold in A.Short-Circuit ProtectionThe MAX16141 EV kit shuts down the output in event the output is shorted to ground. The output will resume normal level, same as the input, when the short at the output is removed.Evaluating other ICs in the MAX16141 FamilyThe MAX16141 EV kit comes with the MAX16141AAF/V+ installed. To evaluate other ICs in the MAX16141 IC family, replace U1 with the desired IC and refer to the MAX16141 IC data sheet for additional detail.Note: Indicate that you are using the MAX16141 when contacting these component suppliers.#Denotes RoHSSUPPLIERWEBSITECentral Semiconductor Kemet Murata/TOKO NXP ON Semiconductor PanasonicPARTTYPE MAX16141EVKIT#EV KitComponent SuppliersOrdering InformationEvaluates: MAX16141 MAX16141 Evaluation KitMAX16141 EV Kit Bill of MaterialsITEM REF_DES DNI/DNP QTY MFG PART #MANUFACTURER VALUE DESCRIPTION COMMENTS1C1, C2-2GRM31CR72E104KW03MURATA0.1UF CAPACITOR; SMT (1206); CERAMIC CHIP; 0.1UF; 250V; TOL=10%; TG=-55 DEGC TO +125 DEGC; TC=X7R2C3-1GRM43DR72E334KW01MURATA0.33UF CAPACITOR; SMT (1812); CERAMIC CHIP; 0.33UF; 250V; TOL=10%; TG=-55 DEGC TO +125 DEGC; TC=X7R3C4-1EEE-FK1V331GP PANASONIC330UF CAPACITOR;SMT (CASE_G); ALUMINUM-ELECTROLYTIC; 330UF; 35V; TOL=20%4C7-1C0805C103K1RAC;GRM21BR72A103KA01;08055C103KAT2AKEMET;MURATA;AVX0.01UFCAPACITOR; SMT (0805);CERAMIC CHIP; 0.01UF; 100V;TOL=10%; MODEL=;TG=-55 DEGC TO +125 DEGC;TC=X7R5C8-1GRM1885C1H102JA01;C1608C0G1H102J080MURATA;TDK1000PFCAPACITOR; SMT (0603);CERAMIC CHIP; 1000PF; 50V;TOL=5%; TG=-55 DEGC TO+125 DEGC6COM, IN_PAD,OUT_PAD, SYSGND,SYSGND_PAD_OUT-5MAXIMPAD N/A MAXIMPADEVK KIT PARTS;MAXIM PAD; NO WIRE TO BESOLDERED ON THEMAXIMPAD7COM_TP1, COM_TP2-25001KEYSTONE N/A TEST POINT; PIN DIA=0.1IN; TOTAL LENGTH=0.3IN; BOARD HOLE=0.04IN; BLACK; PHOSPHOR BRONZE WIRE SILVER PLATE FINISH;8D1-1CMPZ5245B CENTRAL SEMICONDUCTOR15V DIODE; ZNR; SMT (SOT-23); VZ=15V; IZ=0.0085A9D2, D3-2CMHZ5231B CENTRAL SEMICONDUCTOR 5.1V DIODE; ZNR; SMT (SOD-123);VZ=5.1V; IZ=0.02A10D4-1BAV300VISHAY BAV300DIODE; SS; SMT (MICROMELF); PIV=60V; IF=0.25A11EN, FAULT, GATE,OVSET, SLEEP, UVSET-65002KEYSTONE N/ATEST POINT; PIN DIA=0.1IN;TOTAL LENGTH=0.3IN; BOARDHOLE=0.04IN; WHITE;PHOSPHOR BRONZE WIRESILVER;12IN, OUT,SYSGND_OUT, TP1-4108-0740-001EMERSON NETWORK POWER108-0740-001CONNECTOR; MALE;PANELMOUNT; BANANAJACK; STRAIGHT; 1PIN13JU1-JU3-3PEC02SAAN SULLINS PEC02SAAN CONNECTOR; MALE; THROUGH HOLE; BREAKAWAY; STRAIGHT; 2PINS14N1, N2-2NVD6824NLT4G ON SEMICONDUCTOR NVD6824NLT4G TRAN; POWER MOSFET; NCH; DPAK; PD-(90W); I-(41A); V-(100V)15R1-1CSSH2728FT5L00STACKPOLE ELECTRONICS INC.0.005RESISTOR; 2728; 0.005 OHM; 1%; 25PPM; 4W; METAL FOIL16R2-1CRCW121010R0FK VISHAY DALE10RESISTOR; 1210; 10 OHM; 1%; 100PPM; 0.5W; THICK FILM17R3-1TNPW06031K00BE;RG1608P-102-BVISHAY DALE;SUSUMU CO LTD.1KRESISTOR; 0603; 1K OHM;0.1%; 25PPM; 0.10W; THICKFILM18R4-1RG1608P-101-B;ERA-3YEB101VSUSUMU CO LTD.;PANASONIC100RESISTOR; 0603; 100 OHM;0.1%; 25PPM; 0.1W; THICKFILM19R6-R9-4CHPHT0603K1002FGT VISHAY SFERNICE10K RESISTOR; 0603; 10K OHM; 1%; 100PPM; 0.0125W; THICK FILM20R10-1CRCW0603162KFK VISHAY DALE162K RESISTOR; 0603; 162K OHM; 1%; 100PPM; 0.1W; THICK FILMEvaluates: MAX16141 MAX16141 Evaluation KitMAX16141 EV Kit Bill of Materials (continued)ITEM REF_DES DNI/DNP QTY MFG PART #MANUFACTURER VALUE DESCRIPTION COMMENTS21R11-1CRCW0603715KFK VISHAY DALE715K RESISTOR; 0603; 715K OHM; 1%; 100PPM; 0.10W; METAL FILM22R12-R14-3ERJ-3EKF1003PANASONIC100K RESISTOR; 0603; 100K OHM; 1%; 100PPM; 0.1W; THICK FILM23R18-1RC0402JR-070RL;CR0402-16W-000RJTYAGEO PHYCOMP;VENKEL LTD.0RESISTOR; 0402; 0 OHM;5%; JUMPER; 0.063W; THICKFILM24SU1-SU3-3S1100-B;SX1100-B KYCON;KYCON SX1100-B TEST POINT; JUMPER; STR; TOTAL LENGTH=0.24IN; BLACK;INSULATION=PBT;PHOSPHOR BRONZE CONTACT=GOLD PLATED25U1-1MAX16141AAF/V+MAXIM MAX16141AAF/V+EVKIT PART - IC; CONTROLLER; IDEAL DIODE CONTROLLER WITH VOLTAGE AND CURRENT CIRCUIT BREAKER; TQFN16-EP; PACKAGE OUTLINE NO.: 21-0139; PACKAGE CODE: T1644-4; PACKAGE LAND PATTERN: 90-007026PCB-1MAX16141MAXIM PCB PCB:MAX16141-27D5DNP0CMZ5938B CENTRAL SEMICONDUCTOR36V DIODE; ZNR; SMA (DO-214AC); VZ=36V; IZ=0.0104A28D6DNP0CMZ5944B CENTRAL SEMICONDUCTOR62V DIODE; ZNR; SMA (DO-214AC); VZ=62V; IZ=0.006A29C5, C6DNP0N/A N/A OPEN PACKAGE OUTLINE 0805 NON-POLAR CAPACITOR30R15, R16DNP0N/A N/A OPEN PACKAGE OUTLINE 0603 RESISTORTOTAL51Evaluates: MAX16141 MAX16141 Evaluation KitEvaluates: MAX16141MAX16141 Evaluation Kit MAX16141 EV Kit—Top Silkscreen MAX16141 EV Kit—TopMAX16141 EV Kit—BottomMaxim Integrated cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim Integrated product.

To start the MAX16826 EV kit software, click Start | Programs | Maxim MAX16826 Evaluation Kit | Maxim MAX16826 Evaluation Kit that is created during installation. The GUI main window appears as shown in Figure 1.Figure 1. MAX16826 EV Kit Software Main WindowString Current SetThe String Current Set group box is located at the upperleft corner of the main window. Use the scrollbars toadjust the current of the LED strings. The correspondingvalues of the current will be shown in the adjacent editboxes. Press the Read button to read the values from thelinear regulator output registers of the MAX16826. Theequivalent values of the output current will be shown inthe edit boxes.Boost Output ControlThe Boost Output Control Mode group box has thefunctions to control the boost output voltage.To control the boost output voltage manually, click on theradio button next to the Manual Control group box. Usethe scrollbar to adjust the output voltage, and the volt-age value will be displayed in the adjacent edit box. Theactual boost output voltage can be seen in the Read BackValues group box.To use the software automatic control, click on the radiobutton next to the Software Control group box. The editbox next to the Set button is used to change the Drain toGND regulated voltage of the current sink FETs on the LEDstring with the highest voltage drop. This voltage setting willdepend on how much overhead the user is willing to have.If the set value is too low, the LED currents will no longerbe well regulated and may indeed drop because the boostvoltage might fall too low. The scrollbar in this mode willmove automatically to compensate and regulate the outputvoltage. The update rate is approximately once per second.In any case, the channel with the lowest voltage across thesink FET will be regulated to the value in the edit box. DIM Pulse Width Modulation (DPWM)The DPWM group box is located at the center of the mainwindow. The four DIM PWM signals generated by theon-board MAXQ2000 microcontrollers are used to controlthe brightness of the LEDs. Adjust the scrollbars in theDPWM Duty Cycle group box to change the duty cycles of the PWM signals and the values of the duty cycle (%)are shown in the adjacent edit boxes. Check the Set AllChannels to 100% Duty Cycle checkbox to force all channel duty cycles to 100%.In the DPWM Frequency group box, change the DPWMfrequency by adjusting the scrollbar position and pressthe Set button. The frequency value will be shown in theedit box.To guarantee that the leading edge of all the DIM signalsare synchronized, press the Set button in the DPWMFrequency group box.Press the Start button to start to generate the PWM signals.Press the Stop button to stop all PWM signals.StatusThe Status group box is located at the right of the main window. The software reads the external FET drain voltage measurements, and the boost output voltage measurement from the ADC output registers of the MAX16826. The software multiplies the measured values by the appropriate scaling factor and then displays them in the Read Back Values group box.Enter the values into the edit boxes in the Fault Level Set group box to set the fault-detection values. When the value in the Read Back Values group box is less than the fault-detection value, then the color of the read-back value changes to dark green. When the read-back value is 0 to 10% higher than the fault-detection value, the read-back value turns a lime color. If the read-back value is more than 10% higher than the fault-detection value, then the read-back value turns purple. The read-back value turns red when it is more than 20% higher than the fault-detection value.The software also reads the fault register to detect the fault conditions. If a fault condition exists, it will be shown in the String Fault Status group box. See Table 2 for the fault-condition explanations.Press the Read button to update the Status group box. By checking the Automatic Read checkbox, the Status group box will be automatically updated every second. Enable/DisableThe Enable/Disable group box controls the signal on the SYNC/EN pin. Click on the Enable radio button to set the signal high and enable the MAX16826. Click on the Disable radio button to set the signal low and disable the MAX16826.StandbyCheck the Standby checkbox to set the MAX16826 to standby mode. Refer to the MAX16826 IC data sheet for more information regarding standby mode.Table 2. Fault Conditions*Open LED string detection may require multiple flag examination.

This EV kit consists of a controller board and an LED driver board. The break-away slots at the center of the EV kit make it easier for the user to break and separate the controller board from the LED driver board. This is done so that once the evaluation is complete with the included software, the driver board can easily be used in the target application environment with the target system microcontroller.To connect the power, ground, PWM, and the I2C inter-face signals of the boards, attach the ribbon cable to the P1 connector of the controller board and attach the other end of the ribbon cable to the P2 connector of the LED driver board.Controller BoardThe controller board acts as the bridge between the soft-ware in the PC and the actual LED driver board containing the MAX16826. In addition to the USB connectivity, it gen-erates the four adjustable PWM DIM signals that control the brightness of the LEDs. The controller board com-municates with the driver board through the I2C interface, and is able to read or change the values of the registers in the MAX16826.The user can use the MAX16826 evaluation kit software to control the controller board.See Table 1 to control the MAX16826 with a user-supplied PWM signal.LED Driver BoardThe LED driver board is able to drive up to four LED strings (7 LEDs/string). LED strings can be connected to the LED driver board through the P3 connector by using a ribbon cable. Connect all of the anode ends of the LED strings to the P3-1 pin (which connects to the boost out-put) of the P3 connector. Then connect the cathode ends of the LED strings to the P3-2 to P3-5 pins (that connects to the drains of the sink FETs) of the P3 connector. User-Supplied I2C InterfaceTo use the MAX16826 EV kit with a user-supplied I2C interface, install the shunts on pins 2-3 of JU4 and JU5. Connect SDA, SCL, and GND lines from the usersupplied I2C interface to the SDA, SCL, and PGND pads on the MAX16826 controller board.After the LED driver board has broken away from the controller board, the user may connect their supplied I2C, DIM, and power signals to the LED driver board through the P2 connector using a ribbon cable. See Table 4 for the pin description of the P2 connector.Table 4.

MIC33050 600mA 4MHz 切换电源调节器说明书

MIC33050 Evaluation Board4MHz Internal Inductor PWM Buck Regulator with HyperLight Load ®HyperLight Load is a trademark of Micrel, Inc.MLF and Micro LeadFrame are registered trademarks of Amkor Technology, Inc.Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 (408) 944-0800 • fax + 1 (408) 474-1000 • General DescriptionThe MIC33050 is a 600mA 4MHz switching regulatorfeaturing HyperLight Load ®mode. The MIC33050 is highly efficient throughout the entire output current range, drawing just 20µA of quiescent current inoperation. The tiny 3mm x 3mm MLF ®package, in combination with the 4MHz switching frequency, enables a compact sub-1mm height solution with only three external components. The MIC33050 provides accurate output voltage regulation under the most demanding conditions and responds extremely quickly to a load transient with exceptionally small output voltage ripple. Factoring in the output current, the internal circuitry of the MIC33050 automatically selects between two modes of operation for optimum efficiency. Under light load conditions, the MIC33050 goes into HyperLight Load mode. HyperLight Load uses a pulse-frequency modulation (PFM) control scheme that controls the off time at light load. This proprietary architecture reduces the amount of switching needed at light load, thereby increasing operating efficiency. The MIC33050 attains up to 83% efficiency at 1mA output load. As the load current increases beyond approximately 100mA, the device operates using the pulse-width modulation (PWM) method for up to 93% efficiency at higher load. The two modes of operation ensure the highest efficiency across the entire load range.The MIC33050 operates from an input voltage range of 2.7V to 5.5V and features internal power MOSFETs that deliver up to 600mA of output current. This step-down regulator provides an output voltage accuracy of ±2.5% across the junction temperature range of 40ºC to +125ºC. The MIC33050 is available in fixed or adjustable versions supporting an output voltage as low as 0.7V. RequirementsThe MIC33050 evaluation board requires an input power source that is able to deliver greater than 650mA at 2.7V. The output load can either be an active (electronic) or passive (resistive) load.Getting Started1. Connect an external supply to the V IN (J1)terminal . Apply the desired input voltage to V IN (J1) and ground (J2) terminals of the evaluation board, paying careful attention to polarity and supply voltage (2.7V ≤ V IN ≤ 5.5V). An ammeter may be placed between the input supply and the V IN (J1) terminal. Be sure to monitor the supply voltage at the V IN (J1) terminal, since the ammeter and/or power lead resistance can reduce the voltage supplied to the device. 2. Connect a load to the V OUT (J3) and groundterminal (J4). The load can be either passive (resistive) or active (electronic load). An ammeter may be placed between the load and the output terminal. Ensure the output voltage is monitored at the V OUT (J3) terminal. 3. Enable the MIC33050. The MIC33050 evaluationboard has a pull-up resistor to V IN . To disable the device, apply a voltage below 0.5V to the EN (J5) terminal. In the absence of the pull-up resistor, the device is enabled by applying a voltage greater than 1.2V to the EN (J5) terminal. The enable pin must be either pulled high or low for proper operation. Removing the pull-up resistor and leaving the pin floating will cause the regulator to operate in an unknown state. Output VoltageThe MIC33050 evaluation board is available with the following output voltage options listed in Ordering Information .Ordering InformationOutput Voltage (Adjustable Option Only)The output voltage of the MIC33050-AYHL is set by the feedback resistors R2 and R3. Follow the equation and circuit below to determine V OUT :⎪⎭⎫ ⎝⎛+⨯=R3R210.4V V OUT Eq. 1Figure 1. Typical Circuit for MIC33050-AYHL (V OUT = 1.8V)The default output voltage for the evaluation board is set to 1.8V (R2=348k Ω, R3=100k Ω). A different output voltage can be obtained by removing R2 and replacing it with the desired resistance. The equation below can be used to find R2:⎪⎭⎫⎝⎛-⨯=10.4V V R3R2OUTEq. 2Changing the output voltage to 2.5V, assuming R3=100k Ω, can be accomplished via the equation below:⎪⎭⎫⎝⎛-⨯=10.4V 2.5V 100k ΩR2 Eq. 3The result is 523k Ω for R2 which gives an output voltage of 2.5V.HyperLight Load ModeMIC33050 uses a minimum on and off time proprietary control loop (patented by Micrel). When the output voltage falls below the regulation threshold, the error comparator begins a switching cycle that turns the PMOS on and keeps it on for the duration of the minimum-on-time.This increases the output voltage. If the output voltage is over the regulation threshold, then the error comparator turns the PMOS off for a minimum-off-time until the output drops below the threshold. The NMOS acts as an ideal rectifier that conducts when the PMOS is off. Using a NMOS switch instead of a diode allows for lower voltage drop across the switching device when it is on. The asynchronous switching combination between the PMOS and the NMOS allows the control loop to work in discontinuous mode for light load operations. In discontinuous mode, the MIC33050 works in pulse frequency modulation (PFM) to regulate the output. As the output current increases, the off-time decreases, thus provides more energy to the output. This switching scheme improves the efficiency of MIC33050 during light load currents by only switching when it is needed. As the load current increases, the MIC33050 goes into continuous conduction mode (CCM) and switches at a frequency centered at 4MHz. The equation to calculate the load when the MIC33050 goes into continuous conduction mode may be approximated by the following formula:⎪⎭⎫⎝⎛⨯⨯->f 2L D )V (V I OUT IN LOAD Eq. 4As shown in the previous equation, the load at which MIC33050 transitions from HyperLight Load mode to PWM mode is a function of the input voltage (V IN ), output voltage (V OUT ), duty cycle (D), inductance (L) and frequency (f). As shown in Figure 1, as the Output Current increases, the switching frequency also increases until the MIC33050 goes from HyperLight Load mode to PWM mode at approximately 120mA. The MIC33050 will switch at a relatively constant frequency around 4MHz once the output current is over 120mA.Figure 2.

MAX7500 EV Kit Software Main WindowEvaluates: MAX7500–MAX7504MAX7500 Evaluation Kit _______________________________________________________________________________________3E v a l u a t e s : M A X 7500–M A X 7504Detailed Description of HardwareThe MAX7500 evaluation kit (EV kit) is a fully assem-bled and tested surface-mount PCB that evaluates the MAX7500 digital temperature sensor. The MAX7500accurately measures temperature, provides an overtemperature alarm/interrupt/shutdown output, fea-tures three address select lines, and integrates a time-out feature that offers protection against I 2C bus lockups.The EV kit is self-powered from the on-board USB inter-face and requires no external power. The MAX7500 EV kit can also evaluate the MAX7501–MAX7504 ICs.Request free IC samples from the factory when order-ing the MAX7500 EV kit.The MAX7500 EV kit provides an on-board I 2C/SMBus interface and is connected to the computer through the USB port. The EV kit includes Windows 2000/XP and Windows Vista-compatible software that provides a graphical user interface (GUI) for control of the MAX7500’s programmable features and selects between the eight available slave addresses of the MAX7500 IC.Power-Supply OptionsJumper JU1 selects between the MAX7500 EV kit’s power-up options; either on-board through the USB interface or through an external user-supplied DC power supply. The voltage from the USB interface is stepped down to +3.3V through the MAX8512 LDO. To configure these options, set JU1 as desired (see Table 1).MAX7500 Evaluation Kit 4_______________________________________________________________________________________Setting the I2C Slave Address (A2, A1, A0) The MAX7500 has eight available slave addresses that can be selected by setting the A2, A1, and A0 pins either high or low. The EV kit provides jumpers JU2, JU3, and JU4 to set A2, A1, and A0, respectively. JU2 also provides an additional option useful for evaluating the MAX7501–MAX7504 that will be discussed in a later section. The default configuration of the EV kit sets A2, A1, and A0 low, resulting in a slave address of 0x90.User-Supplied I2C/SMBus Interface To use the MAX7500 EV kit with a user-supplied I2C/SMBus interface, first move the shunts of JU6 and JU8 to the 1-2 position. Then, connect the SDA and SCL signals to the corresponding SDA and SCL pads on the MAX7500 EV kit board. R6 and R7 footprints are provid-ed for the option to add pullup resistors if needed.Evaluating the MAX7501–MAX7504 The MAX7500 EV kit can also be configured to accept the MAX7501–MAX7504. To evaluate the MAX7501–MAX7504, replace the IC (U1) and set JU2 to pins 1-3 (RESET input).To utilize the RESET input on the MAX7501–MAX7504, JU14 must also be set accordingly: Pins 1-2 for an external RESET input or pins 2-3 for software control of the RESET input. Note:To apply an external RESET signal, apply a low pulse with a duration of at least 1µs at the RESET pad. Refer to the MAX7501–MAX7504 IC data sheet for additional information.Detailed Description of Software The MAX7500 EV kit software accurately reads temper-ature data with a 0.5°C resolution, sets the upper and lower temperature threshold limits, and configures the behavior of the open-drain overtemperature shutdown (OS) output. The MAX7500 supports eight different I2C slave addresses; configure JU2, JU3, and JU4 to select between different addresses. Check the Shutdown checkbox (Figure 1) to shut down the MAX7500 internal blocks. By pressing the Defaults button, the device is restored to its power-on-reset (POR) state. Refer to the MAX7500–MAX7504 IC data sheet for further details.Reading Temperature Temperature data is displayed on the software main window (Figure 1). To read temperature, press the Read button and the sensor temperature is displayed on the software interface with a 0.5°C resolution. The Auto-Read checkbox is provided to continuously read and display the temperature and limit registers’ data when checked.The OS Fault indicator is displayed under the tempera-ture data on the software’s main GUI. The indicator asserts (turns red) when the OS is asserted. The indica-tor deasserts (turns green) when the OS is deasserted. Refer to the T OS and T HYST Registers section in the MAX7500–MAX7504 IC data sheet for more information.Setting T OS and T HYST Registers The T OS and T HYST registers can be set by writing the appropriate values in the TOS and THYST edit boxes and pressing their respective Write button. The current contents of the T OS and T HYST registers can be read by pressing on the Read button.Configuration Register The Configuration group box sets the fault queue, OS polarity, shutdown control, and whether the OS output functions in comparator or interrupt mode. The Fault Queue drop-down list determines the number of faults necessary to trigger an OS condition. The OS Polarity drop-down list forces the OS polarity to either active-low or active-high. The Shutdown checkbox, when checked, shuts down the internal blocks and drops the supply current to 3µA.The Mode drop-down list selects between running the OS output in comparator or interrupt modes. In com-parator mode, OS is asserted when the temperature rises above the T OS value and is deasserted when the temperature drops below the T HYST value. In interrupt mode, OS is asserted when the temperature rises above the T OS value or falls below the T HYST value and OS is deasserted only after performing a read operation.

To reset the MAX7501–MAX7504, select the Options | Reset I2C (7501-7504Only)menu item from the menu bar. JU14 must be set to pins 2-3 and jumper JU2 must be set to pins 1-3.Simple SMBus CommandsThere are two methods for communicating with the MAX7500, through the MAX7500 EV kit software main window (Figure 1), or through the interface window available by selecting the Options | Interface Diagnostic Window menu item from the menu bar. The Maxim command module interface window (Figure 2)includes a 2-wire interface tab that allows for execu-tion of the frequently used commands.MAX7500 Evaluation Kit 6_______________________________________________________________________________________Figure 2.

A temperature and bias compensated output over-current protection function is implemented by sensing the voltage developed across the on-resistance of the synchronous rectifier MOSFET for optimum cost and performance. This user guide contains the schematic and bill of materials for the IR38063 evaluation board. The guide describes operation and use of the evaluation board itself. Detailed application information for IR38063 is available in the IR38063 data sheet.BOARD FEATURES•PVin = +12V (+ 13.2V Max), No Vcc required.• V out = +1.2V @ 0-25A•Fs=600kHz•L= 0.215uH• C in= 4x22uF (ceramic 1206) + 1x330uF (electrolytic, optional)•Cout =7x47uF (ceramic 0805)Sup IR Buck TMA well regulated +12V input supply should be connected to PVin+ and PVin-. A maximum of 25A load should be connected to VOUT+ and VOUT-. The inputs and output connections of the board are listed in Table I.IR38063 needs only one input supply and internal LDO generates Vcc from PVin. Another internal LDo generates the 1.8V needed by the internal digital circuits. If operation with external Vcc is required, then R25 should be removed and external Vcc can be applied between Vcc+ and Vcc- pins. Vin pin and Vcc pins should be shorted together for external Vcc operation by installing R24.The board is configured for remote sensing. If local sense is desired, R8 should be uninstalled and R16 should be installed instead.I2C/PMBus communication is established through the 4 pin header which allows connection to the SCL/SDA/SALERT and GND lines from the host/dongle. For proper operation in digital communications mode, R35 must always be populated.External Enable signal can be applied to the board via exposed Enable pad and R18 should be removed for this purpose.CONNECTIONS and OPERATING INSTRUCTIONSLA YOUTThe PCB is a 6-layer board. All of layers are 2 Oz. copper. The IR38063 and most of the passive components are mounted on the top side of the board.Power supply decoupling capacitors and feedback components are located close to IR38063. The feedback resistors are connected to the output of the remote sense amplifier of the IR38063 and are located close to the IR38063. To improve efficiency, the circuit board is designed to minimize the length of the on-board power ground current path. Separate power ground and analog ground are used andmay be connected together using a 0 ohm resistor. Table I.
