Fixed Output 1.5 Amp SIP DC/DC Converters

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 ap-

plications. The ﬁxed single output converters offer

both tight regulation and high efﬁciency directly

at the power usage site and are a direct plug-in

Based on ﬁxed-frequency buck switching topology,

the high efﬁciency means very low heat and little

electrical noise, requiring no external components.

The ultra wide input range is 7 to 36 Volts DC.

Protection features include input undervoltage

and short circuit protection, overcurrent and over

temperature shut down. The OKI-78SR is designed

replacement for TO-220 package 78xx series linear to meet all standards approvals. RoHS-6 (no lead)

Typical unit

regulators. Typically, no extra outside components

are required.

hazardous material compliance is speciﬁed as

standard.

Two nominal output voltages are offered (3.3

and 5 VDC), each with 1.5 Amp maximum output.

FEATURES

■ Ultra wide 7 to 36 VDC input range

■ Fixed Outputs of 3.3 or 5 VDC up to 1.5 Amps

■ Vertical SIP-mount, small footprint package

■ “No heat sink” direct replacement for 3-terminal

78xx-series linear regulators

■ High efﬁciency with no external components

■ Short circuit protection
