Non-isolated switching regulators

15 November 2017 Power Electronics / Power Management

Murata has added a 12 V model to its OKI-78SR series of non-isolated switching regulator DC-DC power converters for embedded applications. The fixed single-output converter offers both tight regulation and high efficiency directly at the power usage site, and is a direct plug-in replacement for TO-220 package 78xx series linear regulators.

Rated at 12 V/ 1 A, when powered from a 24 V source, the OKI-78SR-12/1.0-W36-C converter’s efficiency is a very high 95%, eliminating the need for a heatsink that adds cost and increases complexity in the design and manufacturing processes. Cleverly packaged in the form of a three-terminal 78xx linear regulator, the converter operates from a source voltage of 15 to 36 V and is available in both vertical and horizontal mounting options. The package size is just 10,4 x 7, 62 x 16,5 mm.

The OKI-78SR series is suitable in a wide range of applications, including computing, networking, telecommunications, industrial, aerospace and rail. It is ideal for any application where the ambient temperature ranges from -40°C to 85°C, which has a source/system voltage in the range of 15 to 36 V d.c., and where the output requirement is for 12 V at 1 A. Standard features include a factory-set Vout at 12 V d.c., short-circuit/over-current protection, UL/EJ/IEC 60950-1, second edition safety approvals and RoHS compliance.
