Product Details
The MAX17555C evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX17555C, 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 14V to 60V input and provides a 12V, 30mA output. The EV kit is set up to turn ON at 20V (max) and turn OFF at 14V (max) using EN/UV and HYST pins. The step-down converter works at a 70kHz frequency and delivers a peak efficiency of 89.1% with supplied components.
The EV kit is simple to use and easily configurable with minimal external components. The MAX17555C features a programmable input EN/UV, HYST threshold, and an open-drain RESET signal. The device offers built-in hiccup mode protection for overload and short circuit conditions, as well as thermal shutdown. The EV kit is complaint with the CISPR32 class B standard.
