12V DC-DC converter for embedded applications eliminates heatsink
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 95%, eliminating the need for a heatsink that adds cost and increases complexity in the design and manufacturing processes. Packaged in teh same footprint as 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 (0.41 x 0.3 x 0.65 inches).
The OKI-78SR series is aimed at applications such as computing, networking, telecommunications, industrial, aerospace and rail where the ambient temperature ranges from -40 to 85°C. Standard features include a factory-set Vout at 12 Vdc, short-circuit/over-current protection, UL/EJ/IEC 60950-1, second edition safety approvals and RoHS compliance.
