Still Camera)Flash Cellular Camera Phone Flash PDA Camera FlashCamcorder Torch(Flashlight)LampThe PAM2803is a set-up DC-DC converter that delivers a regulated output current.The device switches at a 1.0MHz constant frequency,allowing for the use of small value external inductor and ceramic capacitors.The PAM2803is targeted to be used for driving loads up to 1A from a two-cell alkaline battery.The LED current can be programmed by the external current sense resistor,Rs,connected between the feedback pin (FB)and ground.A low 95mV feedback voltage reduces the power loss in the Rs for better efficiency.With its internal 2A,100device can provide high efficiency even at heavy load.During the shutdown mode,the feedback resistor Rs and the load are completely disconnected and the current consumption is reduced to less than 1uA.The PAM2803is available in the 6-lead SOT-23-6package.LED LED ApplicationsGeneral Descriptio nmΩNMOS switch,the n n n n n n n n n n n n n n n n nTypical

SelectionLED Current SettingThe PAM2803can use small value inductors due to its switching frequency of 1MHz.The value of inductor will focus in the range of 2.2uH to 4.7uH for most PAM2803applications.In typical high c u r r e n t w h i t e L E D a p p l i c a t i o n s ,i t i s recommended to use a 4.7uH inductor.The inductor should have low DCR (DC resistance)to minimize the I R power loss,and it requires a current rating of 2A to handle the peak inductor current without saturating.An input capacitor is required to reduce the input ripple and noise for proper operation of the PAM2803.For good input decoupling,Low ESR (equivalent series resistance)capacitors should be used at the input.At least 2.2uF input capacitor is recommended for most applications.A minimum output capacitor value of 6.8uF is r e c o m m e n d e d u n d e r n o r m a l o p e r a t i n g conditions,while a 10uF-22uF capacitor may be required for higher power LED current.A reasonable value of the output capacitor depends on the LED current.The ESR of the output capacitor is the important parameter to determine the output voltage ripple of the converter,so low ESR capacitors should be used at the output to reduce the output voltage ripple.The small size of ceramic capacitors is an excellent choice for PAM2803applications.The X5R and X7R types are preferred because they maintain capacitance over wide voltage and temperature ranges.It's indispensable to use a Schottky diode rated at 2A with the ing a Schottky diode with a lower forward voltage drop is better to improve the power LED efficiency,and its voltage rating should be greater than the output voltage.I n a p p l i c a t i o n ,t h e O N S e m i c o n d u c t o r MBRA210LT3G is recommended.The LED current is set by the single external Rs resistor connected to the FB pin as shown in the typical application circuit on page 1.The typical FB reference is internally regulated to 95mV.The LED current is 95mV/Rs.It's recommended to use a 1%or better precision resistor for the better LED current accuracy.The formula and table 1for Rs selection are shown as follows:Rs=95mV/I Table 1.Rs Resistor Value Selection 2LEDPCB Layout GuidelinesAs for all switching power supplies,the layout and components placement of the PAM2803is an important step in the design;especially at h i g h p e a k c u r r e n t s a n d h i g h s w i t c h i n g frequencies.The input capacitor and output capacitor should be placed respectively as close as possible to the input pin and output pin of the IC;the inductor and schottky diode should be placed as close as possible to the switch pin by using wide and short traces for the main current path;the current sense resistor should be placed as close as possible between the ground pin and feedback pin.Application InformationStandard Value(Ω)I LED (mA)0.185280.156330.127920.10950Ordering InformationPlease consult PAM sales office or authorized Rep Distributor for detailed

什么是同步整流

同步整流技术是采用通态电阻极低的功率MOSFET来取代整流二极管，因此能大大降低整流器的损耗，提高DC／DC变换器的效率，满足低压、大电流整流的需要。

首先介绍了同步整流的基本原理，然后重点阐述同步整流式DC／DC电源变换器的设计。

字串5关键词：同步整流；磁复位；箝位电路；DC／DC变换器1 同步整流技术概述字串7近年来随着电源技术的发展，同步整流技术正在向低电压、大电流输出的DC／DC变换器中迅速推广应用。

DC／DC变换器的损耗主要由3部分组成：功率开关管的损耗，高频变压器的损耗，输出端整流管的损耗。

在低电压、大电流输出的情况下，整流二极管的导通压降较高，输出端整流管的损耗尤为突出。

快恢复二极管（FRD）或超快恢复二极管（SRD）可达1.0～1.2V，即使采用低压降的肖特基二极管（SBD），也会产生大约0.6V的压降，这就导致整流损耗增大，电源效率降低。

举例说明，目前笔记本电脑普遍采用3.3V甚至1.8V或1.5V的供电电压，所消耗的电流可达20A。

此时超快恢复二极管的整流损耗已接近甚至超过电源输出功率的50％。

即使采用肖特基二极管，整流管上的损耗也会达到（18％～40％）PO，占电源总损耗的60％以上。

因此，传统的二极管整流电路已无法满足实现低电压、大电流开关电源高效率及小体积的需要，成为制约DC／DC变换器提高效率的瓶颈。

同步整流是采用通态电阻极低的专用功率MOSFET，来取代整流二极管以降低整流损耗的一项新技术。

它能大大提高DC／DC 变换器的效率并且不存在由肖特基势垒电压而造成的死区电压。

功率MOSFET属于电压控制型器件，它在导通时的伏安特性呈线性关系。

用功率MOSFET做整流器时，要求栅极电压必须与被整流电压的相位保持同步才能完成整流功能，故称之为同步整流。

为满足高频、大容量同步整流电路的需要，近年来一些专用功率MOSFET不断问世，典型产品有FAIRCHILD公司生产的NDS8410型N沟道功率MOSFET，其通态电阻为0.015Ω。

IR38060 评估板用户指南说明书

USER GUIDE FOR IR38060 EVALUATION BOARD DESCRIPTIONThe IR38060 is a synchronous buckconverter with a PMBus interface, providing a compact, high performance and flexible solution in a small 5mmx6mm PQFN package.Key features offered by the IR38060 include I2C/PMBus configurability of output voltage, soft-start, input UVLO, input overvoltage protection, output overvoltage protection, output overcurrent protection, Power Good, thermal protection and switching frequency. Additionally, the IR38060 also features enhanced line/ load regulation with feed forward, external frequency synchronization with smooth clocking, internal LDO, true differential remote sensing and pre-bias start-up. 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 IR38060 evaluation board. The guide describes operation and use of the evaluation board itself. Detailed application information for IR38060 is available in the IR38060 data sheet.BOARD FEATURES•PVin = +12V (+ 13.2V Max), No Vcc required.• V out = +1.2V @ 0-6A•Fs= 600kHz•L= 0.82uH•C in= 3x22uF (ceramic 1206) + 1x330uF (electrolytic, optional)•Cout =7x22uF (ceramic 0805)Sup IR Buck TMA well regulated +12V input supply should be connected to PVin+ and PVin-. A maximum of 6A load should be connected to VOUT+ and VOUT-. The inputs and output connections of the board are listed in Table I.IR38060 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. For normal, non-tracking operation, R27 should not be populated and a 100 kOhm resistor should be connected from the Track_En pin to P1V8.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 forthis purpose.CONNECTIONS and OPERATING INSTRUCTIONSLA YOUTThe PCB is a 4-layer board. All of layers are 2 Oz. copper. The IR38060 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 IR38060. The feedback resistors are connected to the output of the remote sense amplifier of the IR38060 and are located close to the IR38060.

It is a measure for the noise onthe physical sensor output. It is measured with analog circuit and integrated over 1 second. 3 Maximum deviation from the ideal shape (linear curve)4 Specified range refers to the range for which the humidity or temperature sensor specification is guaranteed.5 For details about recommended humidity and temperature operating range, please refer to section 1.1.6 Time for achieving 63% of a humidity step function, valid at 25°C and 1m/s airflow. Humidity response time in the application depends on the design-in of the sensor.7 Typical value for operation in normal RH/T operating range, see section 1.1. Maximum value is < 0.5 %RH/yr. Value may be higher in environments with vaporized solvents, out-gassing tapes, adhesives, packaging materials, etc. For more details please refer to Handling Instructions.8 Temperature response times strongly depends on the design-in of the sensor in the final application. Minimal response time can be achieved when the thermalizedsensor at T1 is placed on a well conducting surface with temperature T2.Humidity Sensor Performance GraphsSHT30SHT31Figure 2 Tolerance of RH at 25°C for SHT30Figure 3 Tolerance of RH at 25°C for SHT31SHT30Figure 4 Typical tolerance of RH over T for SHT30Figure 5 Typical tolerance of RH over T for SHT31Temperature Sensor Performance GraphsFigure 6Temperature accuracy of the SHT30 sensor at VDD= 4.5V…5.5V.Figure 7 Temperature accuracy of the SHT31 sensor at VDD = 4.5V…5.5V.1.1Recommended Operating ConditionThe sensor shows best performance when operated within recommended normal temperature and humidity range of 5 –60 °C and 20 – 80 %RH, respectively. Long term exposure to conditions outside normal range, especially at high humidity, may temporarily offset the RH signal (e.g. +3%RH after 60h at >80%RH). After returning into the normal temperature and humidity range the sensor will slowly come back to calibration state by itself. Prolonged exposure to extreme conditions may accelerate ageing. To ensure stable operation of the humidity sensor, the conditions described in the document “SHTxx_STSxx Assembly of SMD Packages”, section “Storage and Handling Instructions” regarding exposure to volatile organic compounds have to be met. Please note as well that this does apply not only to transportation and manufacturing, but also to operation of the SHT3x-ARP.2Specifications2.1Electrical SpecificationsTable 3 Electrical specifications, typical values are valid for T=25°C, min. & max. values for T=-40°C … 125°C.2.2Timing Specification for the Sensor SystemTable 4 System Timing Specification, valid from -40 °C to 125 °C and 2.4 V to 5.5 V.2.3Absolute Minimum and Maximum RatingsStress levels beyond those listed in Table 5 may cause permanent damage to the device or affect the reliability of the sensor. These are stress ratings only and functional operation of the device at these conditions is not guaranteed. Ratings are only tested each at a time.Table 5 Minimum and maximum ratings; values may only be applied for short time periods.9 According to ANSI/ESDA/JEDEC JS-001-2014; AEC-Q100-00210 According to ANSI/ESD S5.3.1-2009; AEC-Q100-011.3 Pin AssignmentThe SHT3x-ARP comes in a tiny 8-pin DFN package – see Table 6.Table 6 SHT3x-ARP pin assignment (transparent top view). Dashed lines are only visible if viewed from below. The die pad is internally connected to VSS.3.1Power Pins (VDD, VSS)The electrical specifications of the SHT3x-ARP are shown in Table 3. The power supply pins must be decoupled with a 100 nF capacitor that shall be placed as close to the sensor as possible – see Figure 8 for a typical application circuit. 3.2Temperature and Humidity PinThe physical output of temperature and humidity can be read out at separated pins, as shown in Table 6. Data is supplied as ratiometric voltage output. The specification of the analog voltage signal and its conversion to physical values is explained in Section 4.3.3nRESET PinThe nReset pin may be used to generate a reset of the sensor. A minimum pulse duration of 1 µs is required to reliably trigger a reset of the sensor. If not used it is recommended to leave the pin floating or to connect it to VDD with a series resistor of R ≥2 kΩ. In addition, the nRESET pin is internally connected to VDD with a pull up resistor of R = 50 kΩ (typ.).Figure 8 Typical application circuit. Please note that thepositioning of the pins does not reflect the position on thereal sensor. This is shown in Table 6.3.4Die Pad (center pad)The die pad or center pad is visible from below and located in the center of the package. It is electrically connected to VSS. Hence electrical considerations do not impose constraints on the wiring of the die pad. However, due to mechanical reasons it is recommended to solder the center pad to the PCB. For more information on design-in, please refer to the docu ment “SHTxx_STSxx Design Guide”.4Operation and Communication4.1Start-up of the sensorThe sensor starts up after reaching the power-up threshold voltage V POR specified in Table 3. After reaching this threshold voltage the sensor needs the time t PU until the first measurement signal is available as voltage output on the respective output pins. During that time the temperature and humidity pins have an undefined state.4.2Conversion of the Signal OutputThe physical values as measured by the sensor are mapped to a ratiometric voltage output (V T, V RH as 10 to 90% of V DD). Prior to conversion into a voltage signal, the physical values are linearized and compensated for temperature and supply voltage effects by the sensor. Additionally, the voltage output is calibrated for each sensor. Hence the relationship between temperature and humidity and the voltage output is the same for each sensor, within the limits given by the accuracy (Table 1 and Table 2).This allows to describe the relationship between physical values (RH and T) and the voltage output for temperature and humidity (V T, V RH) through a generic linear formula given by equations (1), (2) and (3); its graphical representation can be found in Figure 9 & Figure 10.Figure 9 Relationship between the ratiometric analog voltage output and the measured relative humidity.Figure 10 Relationship between the ratiometric analog voltage output and the measured temperature[]DDT DD T V V V V 66.875 ⋅+--=⋅+-=︒0.81750.817.545 C T 75.218 (2)[]DDT DDT V V V V 88.375 ⋅+--=⋅+-=︒0.83150.831.549 T 75.393F (3)Equations (2) and (3) describe the conversion formulae for the temperature signal in °C and °F.DDRH DDRH V V V V ⋅+-=⋅+-= 0.81000.810 12512.5 RH (1)Equation (1) describes the conversion formula for the RH signal.5PackagingSHT3x-ARP sensors are provided in an open-cavity DFN package. DFN stands for dual flat no leads. The humidity sensor opening is centered on the top side of the package.The sensor chip is made of silicon and is mounted to a lead frame. The latter is made of Cu plated with Ni/Pd/Au. Chip and lead frame are overmolded by an epoxy-based mold compound leaving the central die pad and I/O pins exposed for mechanical and electrical connection. Please note that the side walls of the sensor are diced and therefore these diced lead frame surfaces are not covered with the respective plating.The package (except for the humidity sensor opening) follows JEDEC publication 95, design registration 4.20, small scale plastic quad and dual inline, square and rectangular, No-LEAD packages (with optional thermal enhancements) small scale (QFN/SON), Issue D.01, September 2009.5.1TraceabilityAll SHT3x-ARP sensors are laser marked for easy identification and traceability. The marking on the sensor top side consists of a pin-1 indicator and two lines of text. The top line consists of the pin-1 indicator which is located in the top left corner and the product name. The small letter x stands for the accuracy class. The bottom line consists of 6 letters. The first two digits XY (=AR) describe the output mode. The third letter (A) represents the manufacturing year (4 = 2014, 5 = 2015, etc). The last three digits (BCD) represent an alphanumeric tracking code. That code can be decoded by Sensirion only and allows for tracking on batch level through production, calibration and testing – and will be provided upon justified request.If viewed from below pin 1 is indicated by triangular shaped cut in the otherwise rectangular die pad. The dimensions of the triangular cut are shown in Figure 12 through the labels T1 & T2.Figure 11 Top View of the SHT3x-ARP illustrating the laser marking..5.2 Package OutlineFigure 12 Dimensional drawing of SHT3x-ARP sensor package.Table 7 Package outline5.3 Land PatternFigure 13 shows the land pattern. The land pattern is understood to be the open metal areas on the PCB, onto which the DFN pads are soldered.The solder mask is understood to be the insulating layer on top of the PCB covering the copper traces. It is recommended to design the solder mask as a Non-Solder Mask Defined (NSMD) type. For NSMD pads, the solder mask opening should provide a 60 μm to 75 μm design clearance between any copper pad and solder mask. As the pad pitch is only 0.5 mm we recommend to have one solder mask opening for all 4 I/O pads on one side.For solder paste printing it is recommended to use a laser-cut, stainless steel stencil with electro-polished trapezoidal walls and with 0.1 or 0.125 mm stencil thickness. The length of the stencil apertures for the I/O pads should be the same as the PCB pads. However, the position of the stencil apertures should have an offset of 0.1 mm away from the center of the package.

RM3253S

RM3253SOff Line AC/DC Switcher ICDescriptionT he RM3253S series switcher ICs cost effectively replace all power supplies up to 5W output power based on unregulated isolated linear transformer (50/60HZ). Unlike conventional PWM (pulse width modulation) controllers, they regulate the output voltage in a new method of off-time modulation control. The controller consists of a VCO (voltage control oscillator), Sense and logic circuit, VDD pin, under-voltage lockout circuit, protection for over-voltage, current limited circuit, leading edge blanking, over load protection and fault condition auto-restart. They are ideal low power AC/DC adapter/charger solution for portable devices,Features• Built-in 800V high voltage BJT and minimal external componets• Low start-up current: Typ.15 μA Max.25 μA• UVLO(under voltage lockout):Typ.12V start-up Typ.6V shut-down• Low operating current:Typ.2 mA Max.5 mA• LEB(leading edge blanking): Typ.300ns• OVP(over voltage protection): Typ.28 V• Operation Frequency: Typ.54KHZ(VDD=21V)• Output Driver Ability: Typ.15 mA• OLP(over load protection)• Universal AC input range• Constant voltage and constant current• SOP-8 package.Applications•AC/DC adapter/charger for cell/cordless phones, digital cameras, MP3/portable audio devices etc• LED Lighting• Replacements for linear transformers and RCC SMTPSPackageApplication CircuitNL+5V_700mAApplication CircuitBlock DiagramPin Connection (Top View)Package FunctionDescription PIN 1: VDD Power Supply PIN 2: NC Not ConnectedPIN 3: Sense Current sensor,it senses the voltage via a sensed resistorPIN 4: OE Emmiter Pin of the power BJT switch.PIN 5、6: OC Output Pin( Connect to switching transformer)PIN 7、8: GNDGroundFunction Description1. Under Voltage LockoutThe turn-on and turn-off thresholds of the RM3253S are fixed internally at 12V/6V. During start-up, the hold-up capacitor must be charger to 12V through the start-up resistor, so that the RM3253S can be enabled. The hold-up capacitor will continue to supply VDD until power can be delivered from the auxiliary winding of the main ransformer, When VDD drop below 6V, IC will be shut-down, and have to start-up again. This UVLO hysteretic window ensures that RM3253S can start-up very well.2. Leading Edge BlankingWhen the power BJT is switched on, a voltage spike will inevitably occur at the sense pin. To avoid premature termination of the switching pulse, a 300 ns leading-edge blanking time is built in RM3253S. Conventional RC filtering can be omitted. During this blanking period, the current-limit comparator is disabled and it cannot switch off the gate driver.3. Voltage Control OscillatorThe sense circuit of RM3253S series will sense the voltage of VDD pin (also the power pin of RM3253S) and then control the frequency of the oscillator. The max frequency of RM3253S series is set to the rated output power point,for example RM3253S is set to 54 KHZ Two signals are generated from the oscillator: the maximum duty cycle signal (DC max) and the clock signal that indicates the beginning of each switching cycle.4. Sense CircuitA resistor voltage divided circuit is connected between the VDD pin and GND pin in order to sample the feed-back voltage at VDD pin. When the voltage of VDD pin exceeds 21V, IC will come into constant voltage control mode,shut- down the output pin and start a bypass circuit. This bypass circuit is linearly controlled by the feedback voltage. When the voltage of VDD pin falls below 21V, the off-time linearly increases in order to have a constant current output.5. Gate OutputUnlike other chips, RM3253S used a constant current circuit to drive the output BJT. The output current is fixed at 15mA, select the appropriate HFE of BJT could have a different output power.6. Fault Condition Auto-restartIn the event of a fault condition such as output over-load or short circuit, RM3253S series enter into auto-restart operation. It is using the turn-on and turn-off threshold again. RM3253S series are working in start mode to protect the system from damage caused by the fault condition.7. Current LimitThe current through the power BJT is detected by the current limit circuit. Then the current flows through the sense-resistor and makes the voltage on Sense pin ramp up. And when this voltage exceeds the internal threshold (Vlimit), the power BJT is turned off immediately.Electrical CharacteristicMAX.UnitMIN.TYP.Item ConditionsSupply VoltageStart-up Current VDD=VDD(ON)-0.1 15 25 uAOperation Voltage 25℃ 21 V Turn-on Threshold Voltage VDD ON 11 12 13 VTurn-off Threshold Voltage VDD OFF 5.5 6 6.5 VOver-voltage Thershold Vovp 28 30 VOscillatorOperation Frequency 25℃45 50 55 KHZ Duty Cycle Vsense=0 75 % Green Mode Frequency 25℃15 20 25 KHZCurrent SensingLeading Edge Blanking 25℃250 300 350 nSCurrent Sense Detection Voltage VDD=15V0.45 0.5 0.55 VElseOutput Delay Time 25℃ 150 nSOutput Driver Current 25℃12 15 18 mAAbsolute Maximum RatingsAttention: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device.Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.DimensionSOP-8SymbolDimensions In Millimeters Dimensions In InchesMin.
