onsemi has launched the FDMF8811, a 100V bridge power stage module for half-bridge and full-bridge isolated DC-DC converters. The 25 A rated device mounted in a PQFN-36 package integrates a 120V driver IC, boost trap diode, and 2 high-efficiency power MOSFETs.

The newly released FDMF8811 reduces the board space required for DC-DC converter design to approximately one-third the size of existing devices. For product designs where size is not a constraint, this device enables increased power delivery within the existing board footprint. This chip is specifically applied to cloud applications such as wireless base stations and power modules, as well as all on-board isolated DC-DC converters, including industrial applications such as motor drives, fans, and HVAC systems.

onsemi, which focuses on integrating all major power components into a single chip, optimizes the design related to driver and MOSFET dynamic performance, system parasitic inductance, and power MOSFET Rds while maintaining the highest possible efficiency. The FDMF8811 delivers over 97% system efficiency in full-bridge 600W applications.

Roberto Guerrero, Senior Marketing Director of onsemi's Cloud Power Solutions, stated, "The FDMF8811 is a breakthrough product that opens a new market segment for applications," and added, "This solution enables higher power density for isolated DC-DC converters, particularly in cloud infrastructure."
