PRODUCT OVERVIEW

Fabricated on a 0.41 by 0.65 inch (10.4 by 16.5 mm) Single Inline Package (SIP) module, the OKI-78SR series are non-isolated switching regulator (SR) DC/DC power converters for embedded applications. The fi xed single output converters offer both tight regulation and high effi ciency 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.

Two nominal output voltages are offered (3.3 and 5 VDC), each with 1.5 Amp maximum output.
