DC-DC Converter
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
385V to 48V 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 48V DC-DC non-isolated
converters.

Note 1: UL’s product certification tests were carried out using 12.5A fast blow fuse. Fuse interruption characteristics have to be taken into account while
designing input traces. User should ensure that Input trace is capable of withstanding fault currents.
Note 2: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: [email protected])
Note 3: Isolation capacitance can be added external to the module (recommended).
