TDK-Lambda i7C Non-Isolated Buck-Boost DC-DC Converters
TDK-Lambda i7C Non-Isolated Buck-Boost DC-DC Converters are non-isolated step-up/step-down converters that are ideal for generating additional DC output voltage rails up to 300W from a single output 12V, 24V, or 48V AC-DC power supply. These highly efficient i7C devices accept a wide DC input and feature a wide output adjustment range. The i7C DC-DC converters feature a Power Good signal, switching frequency synchronization, and output current monitoring. TDK-Lambda i7C Non-Isolated Buck-Boost DC-DC Converters are available in three mechanical configurations: low profile open frame, baseplate construction for conduction cooling, and an integral heat sink for convection or forced air cooling.
