Product Details

Murata 1.5A Single Output Non-Isolated DC-DC Converter - OKI Series

The Murata PS OKI-78SR Series is built on a 10.4 by 16.5 mm, single inline package SIP module, these DC/DC converters are non-isolated switching regulator for embedded applications. Two nominal output voltages are offered, each with 1.5 Amp maximum output. Based on fixed-frequency buck switching topology, the high efficiency means very low heat and little electrical noise, requiring no external components. The ultra-wide input range is 7 to 36 Volts DC. Protection features include short circuit current limit protection. The OKI-78SR switching regulator is designed to meet all standards approvals. RoHS-6 (no lead) hazardous material compliance is specified as standard.
