Product Overview

The R-78HB3.3-0.5L is a 1-output 1.65W through hole-mount non-isolated DC/DC Converter for use with battery powered applications. High input voltage Switching Regulator ideally suited to replace 78xx linear regulators and are pin compatible. The efficiency of up to 96% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs. An input voltage range of up to 8:1 is unsurpassed by any other converter and allows the full stored energy utilization of standard and high voltage batteries. The fully protected output is ideal for industrial applications (especially for industry standard 24VDC bus supplies) and the L-Version with 90° pins allows direct replacement for laid-flat regulators where component height is at a premium. Low ripple and noise figures and a short circuit input current of typically only 15mA round off the specifications of this versatile converter series.
  • Low profile
  • No need for heatsinks
  • Pin-out compatible with LM78XX Linears
  • High voltage input range up to 72V
  • Short circuit protection, thermal shutdown
  • Non-standard outputs available as specials between 3.3 to 24V
