SKU: PHI1071378 Category: Tags: ,


This DC-DC step-down voltage module can convert 6-24V voltage input to 5V, 3A output. The module uses a synchronous rectification IC which enables high-efficiency conversion of up to 97.5% and low static current less to 0.85mA which in turn can save the car battery’s energy. The whole network is also equipped with input reverse polarity protection, output overvoltage protection, short circuit protection plus the flat conductors which reduces module’s heat. The output is a female USB port compatible with iPhone, IPad, and Android smartphones. The module comes in a very compact size and features two solder pads at the back making it possible for integrating into other projects.
