Mouser Electronics is the first distributor to stock the FDMF8811 bridge power stage module from ON Semiconductor. The industry’s first 100V bridge power stage module for half-bridge and full-bridge DC-DC converters, the module uses high-performance PowerTrench MOSFET technology, which reduces switch ringing in converter applications.

The module integrates a 120V driver IC, a bootstrap diode, and two highly efficient power MOSFETs in a PQFN-36 package.

By integrating all of the key power components, the module maintains very high efficiency above 97 % in full-bridge 600W applications. The module’s design optimises driver and MOSFET dynamic performance, system parasitic inductance, and power MOSFET R_DS(ON).

The driver IC features low delay time and matched PWM input propagation delays, which further enhance the device’s performance.

The 25A module reduces the board area required for DC-DC converter designs by approximately one third compared to discrete implementations, enabling engineers to design smaller systems.

It also enables increased power delivery within existing available board area.

It is ideal for cloud applications such as wireless base stations, power modules, and onboard isolated DC-DC converters, as well as industrial applications such as motor drives, fans, and HVAC systems.
