Power
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
converters.
