DC/DC converter range extended for embedded applications

A 12V model has been added by Murata 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 24V 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 15-36V and is available in both vertical and horizontal mounting options. The package size is just 10.4x7.62x16.5mm (0.41x0.3x0.65”).

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

The OKI-78SR series incorporates advanced assembly techniques and the latest fixed switching frequency technology for power conversion available today. The optional packaging configurations, safety features, high reliability, figures for efficiency, thermal management, dynamic load response, industry standard package and OCP protection features offer an unmatched level of performance.
