DC-DC Converters

AC-DC Power Supplies


300W up to 9-53V Input, Buck-Boost Non-isolated DC-DC Converters

The i7C series of non-isolated step-up / step-down converters are ideal for generating additional DC output voltage rails up to 300 W from a single output 12V, 24V or 48V AC-DC power supply. The highly efficient i7C series accepts a very wide DC input and has a wide output adjustment range. Three mechanical configurations are available; low profile open frame, baseplate construction for conduction cooling, or integral heat sink for convection or forced air cooling. A full feature Power Good signal, switching frequency synchronization and output current monitoring option is available.



  • Up to 300W in a 1/16th Brick Pin-Out
  • High Efficiency - Up to 97%
  • Wide 5 to 28V, 8 to 24V or 9.6 to 48V Output Adjustment
  • Wide 9 to 36V or 9 to 53Vdc Input Range
  • Low Component Count With Minimal External Components
  • Low Airflow With Minimal Derating Requirements
