製品概要

The MAX17554B evaluation kit (EV kit) is a fully assembled and tested circuit board that shows the performance of the MAX17554B, 10V to 60V, 50mA, ultra-small, high efficiency, synchronous step-down DCDC converter in an 8-pin TDFN (2mm x 2mm) package. The EV kit is designed to operate over a 10V to 60V input and provides a 5V, 50mA output. The MAX17554B turns on at 42.5V (max) and turns off at 10V (max) input voltage. The step-down converter works at a fixed 70kHz switching frequency and delivers a high light load efficiency of 78.3% with supplied components at 48V IN, 5V 10mA OUT.

The EV kit is simple to use and easily configurable with minimal external components. The MAX17554B features fixed turn ON/OFF input voltage and 70kHz switching frequency. 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.
