Murata Power Solutions Non-Isolated DC-DC Converter, 5.2V DC Output Voltage, 1.5A Output Current, 7.5W OKI-78SR-5/1.5-W36H-C

Murata Power Solutions OKI-78SR-5/1.5-W36H-C is a non-isolated DC-DC converter designed to deliver a fixed 5.2V DC output at 1.5 Amps with a power rating of 7.5 Watts. Packaged in a compact TO-220 SIP module measuring 10.4 mm length, 16.5 mm depth, and 7.6 mm width, it is tailored for embedded electronics requiring efficient and stable voltage regulation.

This converter supports an ultra-wide input voltage range from 7 V to 36 V DC, making it suitable for a variety of power sources. Its fixed-frequency buck switching topology ensures high efficiency of 90.5%, which minimizes heat dissipation and eliminates the need for external heat sinks, enabling compact system designs.

Protection features include short circuit current limit which safeguards the device under fault conditions. The converter provides exceptionally low ripple and noise of 75 mV peak-to-peak for sensitive electronic circuits. Operational temperature spans from -40°C minimum up to 85°C maximum, providing robust performance across industrial and commercial environments.

Designed as a drop-in replacement for traditional 3-terminal 78xx linear regulators, the OKI-78SR module offers improved thermal derating performance and greater power efficiency with no external components required. It meets RoHS compliance for hazardous materials and holds UL/EN/IEC 60950-1, 2nd Edition approvals for safety.

The device features 3 pins, and weighs approximately 2 grams, making it easy to integrate into compact assemblies. With a Mean Time Between Failures (MTBF) of over 78 million hours, it guarantees reliable operation in demanding applications such as industrial automation, instrumentation, telecommunications, and power management in embedded systems.

Ultra-wide 7 to 36 VDC input voltage range. Fixed 5.2 V DC output with 1.5 A current capability. High efficiency at 90.5% for low power loss. Short circuit current limit protection included. Compact TO-220 SIP package for easy PCB mounting.
