PSR-78xxPW PSR-SERIES Rev.04-2015 500 mA Switching Regulator Wide Input Volage Range SIP3 Plastic Package Non-Isolated & Non-Regulated Short Circuit Protection Low Ripple and Noise Mainzer Straße 151–153 D-55299 Nackenheim Tel. +49 6135 7026-0 Fax: +49 6135 931070 www.peak-electronics.de [email protected] The PSR series is a family of cost effective single output buck DC-DC converters. These converters are encapsulated in a non conductive black plastic 3-pin SIP case, continuous short circuit protection with automatic restart, good line / load regulation and ultra low quiescence current. Devices are filled up with flame retardant resin. High performance features include high efficiency operation up to 94%.
