DC-DC Converter

Product Details

The BQ4H136HTx80 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 BusQor® provides an isolated step down voltage from 385 V to 13.6 V intermediate bus with no regulation in a standard half-brick module. The BQ4H136HTx80 converter is ideal for creating the mid-bus voltage required to drive standard DC-DC non-isolated converters.
