DC-DC Converter

Product Details

The BQ4H480FTx64 bus converter is a next-generation, board-mountable, isolated, fixed switching frequency DC-DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The series provides an isolated step down voltage from 385 V to 48 V intermediate bus with no regulation in a standard full-brick module. The BQ4H480FTx64 converter is ideal for creating the mid-bus voltage required to drive standard 48 V DC-DC non-isolated converter systems.
