Features & Applications

The OKI-78SR-3.3/1.5-W36-C is a Part of 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.

Two nominal output voltages are offered (3.3 and 5 VDC), each with 1.5 Amp maximum output. Based on fi xed-frequency buck switching topology, the high effi ciency means very low heat and little electrical noise, requiring no external components. The ultra wide input range is 7 to 36 Volts DC.

Features:

  • Ultra wide 7 to 36 VDC input range
  • Fixed Outputs of 3.3 or 5 VDC up to 1.5 Amps
  • Vertical or horizontal SIP-mount, small footprint package
  • “No heat sink” direct replacement for 3-terminal 78xx-series linear regulators
  • High effi ciency with no external components
  • Short circuit protection
  • Outstanding thermal derating performance
