The MAX15023 evaluation kit (EV kit) is a fully assem-
bled and tested PCB that contains all the components
necessary to evaluate the performance of the
MAX15023 dual, synchronous step-down controller.
The MAX15023 EV kit requires a 9V to 16V DC power
supply, which provides up to 5A for normal operation.
The EV kit provides 1.2V/10A and 3.3V/5A at the out-
puts. Each step-down controller operates 180° out-of-
phase to reduce input-voltage ripple and total RMS
input ripple current.
The converters’ switching frequency is programmed to
500kHz. The EV kit includes individual enable control
PCB pads for each converter and power-good outputs
for both converters that can be configured for power-
supply sequencing of the outputs.
