Recom SIP3 Single Output DC/DC Converter R-78(H/B)xx(L) Series

Recom Brand: Recom

A range of Recom DC to DC Single Output converters from the R-78xx-1.0 and R-78HBxx series. These switching regulators are ideally suited to replace 1A 78xx linear regulators and are pin compatible. The convertors have a high voltage input range, and an efficiency of up to 97%, meaning that very little energy is wasted as heat, so there is no need for any heat sinks with their additional space.

The L-Version with 90° pins allows direct replacement for laid-flat regulators where component height is at a premium. The low ripple and noise figures, and a short circuit input current of typically only 15mA, round off the specifications of this versatile converter series.

Typical applications include telecommunication, automotive, industrial, aerospace and battery powered applications.

  • Efficiency up to 94%, no need for heat sinks
  • Pin-out compatible with LM78xx Linear Regulators
  • Wide input range (4.75V to 18V)
  • Short circuit protection, thermal shutdown
  • Non standard outputs available as specials
  • Low ripple and noise
  • No heatsink required
  • Low profile: 11.5(L) x 7.5(W) x 10.2(H)mm
  • Available in the R-78xx-1.0 and R-78HBxx series
  • Available with Straight or 90° pins (L version)
