製品概要

The MAX17553B evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX17553B, 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 6V to 60V input and provides a 5V, 50mA output. The EV kit isset up to turn ON at 8V(max) and turn OFF at 6V(max)using EN/UV and HYST pins. The step-down converteris programmed to switch at a 200kHz frequency anddelivers a peak efficiency of 93.6% with suppliedcomponents.

The EV kit is simple to use and easily configurable with minimal external components. The MAX17553B 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.
