The industry's first 100V bridge power stage module for "half-bridge" and "full-bridge" DC/DC converters, the FDMF8811 module utilizes high-performance PowerTrench™ MOSFET technology, which reduces switch noise in converter applications.
The ON Semiconductor FDMF8811 module integrates a 120V driver IC, a startup diode, and two highly efficient power MOSFETs into a PQFN-36 package. By integrating all key power components, the module maintains very high efficiency exceeding 97 percent in 600W full-bridge applications. The module's design optimizes the dynamic performance of the driver and MOSFETs, the system's parasitic inductance, and the power MOSFET's RDS(ON). The driver IC features low time delay and matching PWM input propagation delays, further enhancing the device's performance.
The 25 A 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. The module also allows for greater power delivery within the existing available board area. The FDMF8811 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.
