Evaluates: MAX15062C in
12V Output-Voltage Application
MAX15062C 12V Evaluation Kit
General Description
The MAX15062C 12V evaluation kit (EV kit) is a fully
assembled and tested circuit board that demonstrates the
performance of the MAX15062C 60V, 300mA ultra-small,
high-efficiency, synchronous step-down converter. The
EV kit operates over a wide input voltage range of 14V
to 60V, and provides up to 300mA load current at 12V
output voltage. The device features undervoltage lockout,
overcurrent protection, and thermal shutdown. The EV kit
switches at a frequency of 500kHz, and delivers a peak
efficiency of 95% with the supplied components.
The EV kit comes installed with the MAX15062CATA+
in an 8-pin (2mm x 2mm) lead(Pb)-free/RoHS-compliant
TDFN package.

● 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, JU2
(EN/UVLO).
2) Verify that jumper JU3 (MODE-PFM operation) is
open.
3) Set the electronic load to constant-current mode,
300mA, and disable the electronic load.
4) Connect the electronic load’s positive terminal to the
VOUT PCB pad. Connect the negative terminal to the
GND PCB pad.
5) Connect the voltmeter across the VOUT and GND
PCB pads.
6) Set the power-supply output to 24V. Disable the
power supply.
7) Connect the 24V power-supply output to the VIN PCB
pad. Connect the supply ground to the GND PCB pad.
8) Turn on the power supply.
9) Enable the electronic load and verify that output volt-
age is at 12V with respect to GND.
10) Vary the input voltage from 14V to 60V.
11) Vary the load current from 1mA to 100mA and verify
that output voltage is 12V.
