Evaluates: MAX77503

MAX77503 Evaluation Kit

General Description

The MAX77503 evaluation kit (EV kit) is a fully assem-

bled and tested PCB that demonstrates the MAX77503

synchronous step-down (buck) converter. The EV kit is a

step-down voltage regulator circuit using MAX77503 that

is capable of 3V to 14V input, 1.5A continuous load, and

output voltage adjustable between 0.8V and 5V (internal

feedback options) or 1.55V and 99% of the input voltage

(external feedback option).

The EV kit features a dual-range electronic load that

allows easy evaluation of loading use cases for the buck

converter circuit. Steady-state, transient, or random load

profiles can be programmed.

PC to run a graphical user interface (GUI) for easy

control of the MAX77503 registers as well as the on-board

electronic load.
