Series Headline Encapsulated Non-Isolated Switching Regulator DC-DC
Series Description Encapsulated in a 0.47 x 0.69 inch (11.9 x 17.6 mm) vertical or horizontal package, the OKI-78SR-E series are non-isolated switching regulator (SR) DC-DC power converters for embedded applications. The fixed single output converters offer both tight regulation and high efficiency directly at the power usage site and are a direct plug-in replacement for TO-220 package 78xx series linear regulators. Typically, no extra outside components are required.

Three nominal output voltages are offered (3.3, 5 and 12 VDC), up to 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 3.3 and 5Vout models have an ultra wide input range of 7 to 36 Volts DC and the 12Vout model has an input voltage range of 15 to 36V.

Protection features include short circuit current limit protection. The OKI-78SR-E is designed to meet all standards approvals. RoHS-6 (no lead) hazardous material compliance is specified as standard.
