300W, 9 to 53V or 9 to 36V Input Non-Isolated
Buck-Boost DC-DC Converter
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.
