• MAXM15066EVKIT# Equipment Setup and Test Procedure 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) Set the power supply at a voltage between 4.5V and 60V. Then, disable the power supply. 2) Connect the positive terminal of the power supply to the VIN PCB pad and the negative terminal to the nearest GND PCB pad. Connect the positive termi - nal of the 300mA load to the VOUT PCB pad and the negative terminal to the nearest GND PCB pad. 3) Connect the DVM (DMM in voltage-measurement mode) across the VOUT PCB pad and the nearest GND PCB pad. 4) Verify that shunt is not installed on jumper J1 (see Table 1 for details). 5) Turn on the DC power supply. 6) Enable the load. 7) Verify that the DVM displays 5V.

Maxim Integrated │ 3 www.maximintegrated.com Evaluates: MAXM15066 5V Output-Voltage Application MAXM15066 5V Output Evaluation Kit Hot-Plug-In and Long Input Cables The MAXM15066 EV kit PCB provides an optional electrolytic capacitor (C2, 4.7µF/100V) to dampen input voltage peaks and oscillations that can arise during hot- plug-in and/or due to long input cables. This capacitor limits the peak voltage at the input of the MAXM15066 power module, when the EV kit is powered directly from a precharged capacitive source or an industrial backplane PCB. Long input cables, between input power source and the EV kit circuit can cause input-voltage oscillations due to the inductance of the cables. The equivalent series resistance (ESR) of the electrolytic capacitor helps damp out the oscillations caused by long input cables. Further, capacitor C1 (0.1µF/100V), placed near the input of the board, helps in attenuating high frequency noise. Mode of Operation The MAXM15066 features PFM mode of operation to increase the efficiency at light-load condition. If the MODE pin is left unconnected during powerup, the module operates in PFM mode at light loads. If the MODE pin is connected to GND during power-up, the part operates in constant-frequency PWM mode at all loads. See Table 2 for J2 settings. Internal LDO An internal regulator provides a 5V nominal supply to power the internal functions of the module. The output of the linear regulator (VCC) should be bypassed with a 1µF capacitor C4 to GND. *Default position #Denotes RoHS compliant.
