Evaluates: MAX38800 MAX38800 Evaluation Kit General Description The MAX38800 evaluation kit (EV kit) serves as a reference platform for evaluating the MAX38800 voltage regulator IC. This single-chip, integrated switching regulator provides an extremely compact, highly efficient, fast, accurate and reliable power delivery solution for lowoutput voltage applications. The MAX38800 has different programmability options to enable a wide range of configurations. The EV kit consists of a fully-assembled and tested Printed Circuit Board (PCB) implementation of the MAX38800. Jumpers, test points, and input/output connectors are included for flexibility and ease-of-use. Refer to the data sheet for ordering information and more details.

If the on-board 1.8V LDO is active (the shunt on jumper J4 is in place), the output voltage can be used for the purpose. Installing a shunt on J15 (4-6) pulls the OE signal high to 1.8V through a 20kΩ resistor. To shut down the regulator a shunt needs to be installed on J10. This forces the OE pin low. Procedure Status Pin ●● ●● ●● ●● ●● MAX38800 EV kit 12V, 10A DC power supply Load capable of sinking 7.5A Digital voltmeter Oscilloscope The EV kit is fully assembled and tested. Follow the steps below to verify the board operation. Caution: Do not turn on power supply until all connections are completed. 1) Connect a 12V power supply to the VDD1 and GND1 banana jacks. 2) Make sure the shunt is installed on: a) J16 (1-2) to close the sense line. b) J4 (1-2) to power up the on-board LDO which regulates 1.8V. c) J12 (1-2) to provide the 1.8V bias supply to the regulator from the on-board LDO. d) J15 (3-5) to pull up the STAT pin. e) J15 (4-6) to pull up the OE pin. 3) 4) 5) Connect a voltmeter to the VOUT and GND banana jacks (J8, J11, J13, and J14 can be used as well). Turn on the power supply. Verify that the voltmeter reads 3.3V. The MAX38800 has an open collector status (STAT) output to report fault or output undervoltage event. Install a shunt on J15 (3-5) to pull up this pin to VCC through a 20kΩ resistor. Since STAT pin is 3.3V tolerant, a shunt on J15 (1-3) can be installed to pull up this pin through a 20kΩ resistor to the 3.3V provided by the on board regulator U3 (install a shunt on J5 (3-4) to enable the LDO). Scenario Selection Several parameters of the MAX38800 can be programmed to allow optimization for specific applications. By selecting the appropriate value of resistor R_SEL (R1) and capacitor C_SEL (C4), the optimum set of parameters (scenario) can be programmed. While R_SEL selects the proper scenario, C_SEL determines the nominal FSW. The MAX38800 features a configuration table to provide a wide range of options. Table 1 shows the scenario table for MAX38800. Detailed Description of Hardware The MAX38800 provides compact, high-efficiency power delivery for precision outputs that demand fast transient response. The 19-ball (2.2mm x 2.8mm) CSP package minimizes the PCB area. The EV kit is preset for 3.3V output and can provide up to 7.5A from a 6.5V to 14V input supply. Bias Supply The MAX38800 EV kit has an on-board LDO (U2) that can provide the required 1.8V VCC bias voltage to both the regulator and pullup voltage for the Output Enable (OE) input. This allows testing the part using a single external power supply. To enable the on-board LDO install the shunt on jumper J4. To effectively use the LDO to supply the VCC bias voltage to the regulator also install the shunt on jumper J12. In order to properly measure the efficiency of the regulator, the LDO should not be active. The shunts on J4 and J12 need to be removed to disable the LDO. An external 1.8V, 0.1A current-limited power supply needs to be connected between J12-2 and ground. The same signal should be connected to J10 (1-2) to pull up the OE pin. www.maximintegrated.com Maxim Integrated │ 2 Evaluates: MAX38800 MAX38800 Evaluation Kit Setting the Output Voltage The output voltage of MAX38800 depends both on the reference voltage (VREF) and the resistor divider ratio. Equation 1 R6 VOUT = VREF × 1 + R9 The reference voltage is selected through RSEL (see Table 1) and can be either internal or external (refer to the data sheet for more details). In order to optimize the common mode rejection of the error amplifier, choose the voltage divider resistors so that their parallel resistance RPAR is as close as possible to 2kΩ. Equation 2 Operation with External VREF When using an external reference adopt the configuration shown in Figure 1. Once OE is asserted, the regulator briefly discharges the SENSE- node and releases it as regulation begins. In this case, the soft-start ramp is determined by the external low-pass filter time constant. The external filter time constant needs to be lower than TSS/3 in order to avoid premature assertion of STAT pin while the output voltage is still ramping. The external reference voltage can be applied prior to enabling the regulator, or ramped up right after enable is asserted. In both cases, the low-pass filtered reference voltage at SENSE- pin must reach its final value within TSS. Typical values for the filter components are: R R 6 VOUT × PAR = VREF R PAR R= 9 R6× R 6 − R PAR ●● RF = 2.2kΩ ●● CF = 0.22μF where, R6 = Top divider resistor R9 = Bottom divider resistor RPAR = Desired parallel resistance of R6 and R9 VOUT = Output voltage VREF = Reference voltage Table 1.

Output Voltage Monitoring J11 and J13 monitor the output voltage. These test points should not be used for loading. Use scopejack J14 to monitor the output voltage ripple on an oscilloscope. Efficiency Measurement The following steps describe how to measure the regulator efficiency. 1) Connect a 12V power supply to the VDD1 and GND1 banana jacks. To avoid the input voltage to drop at high load due to power losses on connection cables connect the sense lines of the power supply to VDD1 and GND1 headers. 2) Connect an external 1.8V, 0.1A current limited power supply between J12-2 and ground. 3) Connect the same power supply to J10-1 to enable the regulator. VCC CVCC 4) Connect a load to the VOUT and GND banana jacks for better results. J8 can also be used for low currents. 5) Make sure the shunt is installed on J16 (1-2) to close the sense line. 6) Remove all the other jumpers. 7) Connect a voltmeter to J11 or J13. 8) Turn on the power supply. 9) Measure VIN, IIN, VOUT, IOUT, VBIAS, and IBIAS. 10) Calculate the efficiency as: Equation 3 VOUT × I OUT η= (V × I ) + ( V BIAS × IBIAS ) IN IN VDDH CIN VCC VDDH MAX38800 CBST VOUT BST RSTAT LOUT VX ROE STAT SENSE+ OE SENSE- AGND C_SEL PGM GND RFB1 RF CF RFB2 VREF COUT Kelvin Connection to Load R_SEL Figure 1.
