Product Details
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.
Vertical SIP or horizontal mount, small footprint,
in an Encapsulated package
No heat sink” direct replacement for 3-terminal
78xx-series linear regulators
High efficiency with no external components
Short circuit protection
Outstanding thermal derating performance
