Micrel MIC28512 70V 2A 同步降压电源评估板说明书
MIC28512 Evaluation Board70V/2A Synchronous Buck RegulatorGeneral DescriptionMicrel’s MIC28512 is a synchronous step-down regulatorfeaturing unique adaptive on-time control architecture withintegrated power MOSFETs. The MIC28512 operates overan input supply range of 4.6V to 70V, and can be used tosupply up to 2A of output current. The output voltage isadjustable down to 0.8V with a guaranteed accuracy of±1% from 0°C to 85°C. The device operates with aprogrammable switching frequency from 200kHz to680kHz (nominal).The MIC28512-1 uses the HyperLight Load®architectureto operate in pulse-skipping mode at light load whilefunctioning in fixed-frequency CCM mode from mediumload to heavy load. The MIC28512-2 utilizes Hyper SpeedControl TM architecture, operating in fixed-frequency CCMmode under all load conditions.Datasheets and support documentation are available onMicrel’s web site at: .RequirementsThe MIC28512 evaluation board requires only a singlepower supply with at least 5A current capability. Forapplications where V IN is less than +5.5V, the internal LDOcan be bypassed by tying VDD to VIN.PrecautionsThe MIC28512 evaluation board does not have reversepolarity protection. Applying a negative voltage to the VINand GND terminals can damage the device. The maximumV IN of the board is rated at 70V; exceeding 70V candamage the device.Ordering InformationPart Number DescriptionMIC28512-1YML EVMIC28512 Evaluation BoardMIC28512-2YML EVEvaluation BoardGetting Started1. Connect VIN SupplyConnect a supply to the VIN and GND terminals, paying careful attention to the polarity and the supply range (4.6V < V IN < 70V). Monitor I IN with a current meter and monitor input voltage at VIN and GND terminals with a voltmeter. Do not apply power until Step 4. 2. Connect Load and Monitor InputConnect a load to the VOUT and GND terminals. The load can be either a passive or an active electronic load. A current meter can be placed between theVOUT terminal and load to monitor the output current. Ensure the output voltage is monitored at the VOUT terminal. 3. Enable InputThe EN terminal has an on board 100k Ω pull-up resistor (R16) to VIN, which allows the output to be turned on when PVDD exceeds its UVLO threshold. An EN (J16) connector is provided on the evaluation board for ease-of-access to the enable feature.Applying an external logic signal on the EN terminal to pull it low or using a jumper to short the EN terminal to the GND terminal will disable the MIC28512 evaluation board. 4. Apply PowerApply V IN and verify that the output voltage regulates to the set voltage.Evaluation Board DescriptionThe basic parameters of the evaluation board are: • Input range: 4.6V to 70V• Output range: 0.8V to 0.85V × V IN at 2A.(For more detailed information, refer to TypicalCharacteristics section. Note that 0.85V is the maximum duty cycle of the MIC28512 controller) • 300kHz switching frequency (Adjustable 200kHz to 680kHz)Feedback ResistorsWith Jumper J11 in place, the output voltage is set to 5.0V as determined by the feedback dividers R1 and R11. Jumper J8 sets the output voltage to 3.3V. With jumper J7 in place the output is set by modifying R9, as illustrated in Equation 1:+×=9R 1R 1V V REF OUTEq. 1Where:V REF = 0.8V, and R1 is 10.0kΩ.With jumpers J11, J8, and J7 removed, the output regulates at the 0.8V reference voltage. All other voltages not listed can be set by modifying R9 with Jumper J7 installed according to Equation 2:REFOUT REFV V V R1R9-×=Eq. 2Jumper J12 shorts out the feedback and forces the converter to operate open loop and approach 100% duty cycle.SW NodeUse test point J1 (V SW ) for monitoring the power MOSFET switching waveform.Current LimitThe MIC28512 uses the R DS(ON) and external resistor connected from ILIM to the SW node to decide the current limit (see Figure 1).Figure 1. MIC28512 Current-Limiting CircuitIn each switching cycle of the MIC28512 converter theinductor current is sensed by monitoring the low-side MOSFET in the OFF period. The sensed voltage V (ILIM) is compared with the power ground (PGND) after a blanking time of 150ns. In this way, the drop voltage over the resistor R22 (V CL ) is compared with the drop over the bottom FET generating the short current limit. The small capacitor (C18) connected from ILIM to PGND filters the switching node ringing during the off time which allows a better short-limit measurement. The time constant created by R22 and C18 should be much less than the minimum off time.The V CL drop allows programming of short limit through the value of the resistor (R22). If the absolute value of the voltage drop on the bottom FET is greater than V CL , V (ILIM)is lower than PGND and a short-circuit event is triggered.A “hiccup” soft-start cycle is generated, reducing the stress on the power switching FETs while protecting the load and supply during severe short conditions.The short circuit current limit can be programmed by using Equation 3:()CLCLDS(ON)PP L CLIM I V R )5.0ΔI (I 22R +××=- Eq. 3Where:I CLIM = Desired current limitR DS(ON) = On-resistance of low-side power MOSFET, 28mΩ typicallyV CL = Current-limit threshold (typical absolute value is 14mV, per the Electrical Characteristics section in the MIC28512 datasheet)I CL = Current-limit source current (typical value is 70µA, per the Electrical Characteristics section in the MIC28512 datasheet).ΔI L(PP) = Inductor current peak-to-peak The peak-to-peak inductor current ripple is:Lf V )V (V V I sw IN(MAX)OUT IN(MAX)OUT L(PP)×××=∆-Eq. 4In case of hard short, the short current-limit threshold (V CL )is reduced by half to the short-circuit threshold. This allowsan indefinite hard short on the output without any destructive effect. It is critical to make sure that theinductor current used to charge the output capacitance during soft start is below the foldback short-circuit level; otherwise the supply can go into hiccup mode and latch up at start up. This should be verified over the operating temperature range as well.The MOSFET R DS(ON) varies 30% to 40% with temperature. Therefore, it is recommended to add a 50% margin to I CL in Equation 4 to avoid false current limiting due to increased MOSFET junction temperature rise. Table 1 shows typical output current limit value for a given R22.Table 1. R22 Typical Output Current-Limit ValueR22 Typical Output Current Limit (V IN = 12V, V OUT = 5V, L = 8.2µH)2.21kΩ 4.3A 1.82kΩ3.0AThe MIC28512 evaluation board was designed with a 8.2µH inductor for operation at 300kHz at 5V output. The typical value of R WINDING(DCR) of this particular inductor is 44mΩ.Setting the Switching FrequencyThe MIC28512 switching frequency can be adjusted by changing the value of resistor R17. The top resistor (R19) is set at 100kΩand is connected between VIN and FREQ. R4 is connected from the FREQ input to PGND and sets the switching frequency according to Equation 4.Figure 2. Switching Frequency Adjustment17R 19R 17R f f O ADJ _SW +×=Eq. 4Where:f O = Switching frequency when R17 is open, per the Electrical Characteristics section in the MIC28512 datasheet.For a more precise setting, it is recommended to use the Figure 3:Figure 3.
