Product Details

The BQ4H136EEC45 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® series provides an isolated step down voltage from 385 V to 13.6 V intermediate bus with no regulation in a extended standard eighth brick module. The BQ4H136EEC45 converter is ideal for creating the mid-bus voltage required to drive standard DC-DC non-isolated converters.
