Data Sheet

i7C Series
300W, 9 to 53V Input Non-Isolated
Buck-Boost DC-DC Converter
i7C Series
1
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 effi cient i7C series accepts a very wide DC input and has a wide output adjustment range. Three
mechanical confi gurations are available; low profi le 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.
