OKI-78SR-E Series
Encapsulated Non-Isolated Switching Regulator DC-DC Typical units FEATURES PRODUCT OVERVIEW
7-36Vin (3.3 & 5Vout), 15-36Vin (12Vout) Encapsulated in a 0.47 x 0.69 inch (11.9 x
17.6 mm) vertical or horizontal package, the OKI78SR-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.
Fixed Output: 3.3 or 5V @ 1.5A or 12V @ 1.0A

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

UL/EN/IEC 60950-1, 2nd Edition safety approvals 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 …
