400-750W, 9 to 18V, 18 to 32V or 18 to 60V Input
Non-Isolated Step Down DC-DC Converter
The i7A series of up to 750W non-isolated DC-DC step-down converters are ideal for creating additional high current/high power 33A, 45A and 60A output voltage
rails from a single output 12V, 24V, 36V or 48V AC-DC or DC-DC power supply. The highly efficient i7A series has low ripple, excellent dynamic response under
sudden load changes, accepts a wide DC input with a wide output adjustment range and optional current limit (OCP) adjust. Three mechanical configurations are
available; low profile open frame, baseplate construction for conduction cooling, or models with an integral heat sink for convection or forced air cooling. The i7A
series expands upon TDK-Lambda’s existing 100 to 250W rated i3A / i6A series and reduces the need to parallel modules.
