The AEK-POW-100W4V1 is a very compact DC-DC converter for automotive and transportation applications which allows regulating the output voltage in the following modes: fixed outputs and Programmable Power Supply (PPS) in 20 mV steps. The board allows setting the output current from a min. of 0.05 A to a max. of 5 A for the entire output voltage range in 50 mA steps. It features several protection systems, such as short-circuit, overcurrent and thermal protection. The AutoDevKit software library includes dedicated components able to configure and drive the board via ST microcontrollers.
