OKI-78SR 1.5A DC/DC Converters

Murata Power Solutions Okami™ OKI-78SR Series 1.5A DC/DC Converters are fixed output SIP converters fabricated on a 0.41" x 0.65" (10.4mm x 16.5mm) module. These non-isolated switching regulators (SR) DC/DC power converters are for embedded applications. The series 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. Typically, no extra outside components are required. Murata Okami OKI-78SR Series 1.5A DC/DC Converters feature an ultra-wide 7VDC to 36VDC input range. Two nominal output voltages are offered (3.3VDC and 5VDC), each with 1.5A maximum output. Based on a fixed-frequency buck switching topology, the high efficiency means very low heat and little electrical noise, requiring no external components.
