100-V bridge power stage module suits half-/full-bridge DC/DC converters

The FDMF8811 100-V bridge power stage module targets half-bridge and full-bridge isolated DC/DC converters. The 25-A device integrates a 120-V driver IC, a bootstrap diode, and two power MOSFETs in a PQFN-36 package.

The power stage module reduces the board area required for DC/DC converter designs by approximately one-third compared to discrete implementations. The device is useful in cloud applications such as wireless base stations, power modules or any on-board, isolated DC/DC converter, and industrial applications such as motor drives, fans, and HVAC. The FDMF8811 delivers system efficiencies in excess of 97% in full-bridge 600-W applications. It is available now in clip bond PQFN-36 packaging and priced at $3.50 per unit in 10,000-unit quantities.
