General Description

The MAX15062A evaluation kit (EV kit) is a fully assem-

bled and tested circuit board that demonstrates the

performance of the MAX15062A 60V, 300mA ultra-small,

high-efficiency, synchronous step-down converter. The

EV kit operates over a wide 4.5V to 60V input voltage

range, and provides up to 300mA at the preset 3.3V out-

put. The device features undervoltage lockout, overcur-

rent protection, and thermal shutdown. The EV kit switch-

es at a fixed frequency of 500kHz, and delivers a peak

efficiency of 90% with the supplied components.

The EV kit comes installed with the MAX15062AATA+

in an 8-pin (2mm x 2mm) lead(Pb)-free/RoHS-compliant

TDFN package.

MAX15062A Evaluation Kit Evaluates: MAX15062A Quick Start Detailed Description Recommended Equipment ● MAX15062A EV kit ● 60V adjustable, 0.5A DC power supply ● Electronic load up to 300mA ● Voltmeter Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. 1) Verify that shunts are installed on jumpers JU1 and JU2 (EN/UVLO).

MAX15062A Evaluation Kit Evaluates: MAX15062A Active-Low Open-Drain Reset Output (RESET) The EV kit provides a PCB pad to monitor the status of the RESET output. RESET goes high when VOUT rises above 95% (typ) of its nominal regulated output voltage. When VOUT falls below 92% (typ) of its nominal regulated voltage, RESET is pulled low. PFM or Forced-PWM Mode (MODE) The EV kit includes a jumper (JU3) to program the mode of operation of the converter.
