TDK-Lambda I7A series non-isolated DC-DC step-down converters are ideal for creating additional high current or high power 33A and 45A output voltage rails from a single output 24V, 36V or 48V AC to DC or DC to 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.

Wide 3.3 to 18V or 3.3 to 24V output adjustment
18 to 32V or 18 to 60V input ranges
Low component count with minimal external components
Minimal derating requirements in low airflow environments
