描述

The MAX17553A evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX17553A, a 4V to 60V, 50mA, Ultra-Small, High Efficiency, Synchronous Step-Down DC-DC Converter in an 8-pin TDFN (2mm x 2mm) package. The EV kit is designed to operate over a 4.5V to 60V input and provides a 3.3V, 50mA output. The EV kit is set up to turn ON at 8V(max) and turn OFF at 4.4V(max) using EN/UV and HYST pins. The step-down converter is programmed to switch at a 150kHz frequency and delivers a peak efficiency of 91% with supplied components.

The EV kit is simple to use and easily configurable with minimal external components. The MAX17553A features programmable input EN/UV and HYST threshold, programmable frequency, and an open-drain active-low RESET signal. The device offers built-in hiccup mode protection for overload and short circuit conditions, and thermal shutdown. The EV kit is complaint with CISPR32 class B standard.
