FDMF8811

High Performance 100V Bridge Power

Stage Module

The 100V Bridge Power Stage (BPS) Module is a fully optimized,

compact, integrated MOSFET plus driver power stage solutions for high

current DC-DC switching applications. The FDMF8811 integrates a

driver IC, two power MOSFETs and a bootstrap diode into a thermally

enhanced, compact 6.0 mm x 7.5 mm PQFN package. The PQFN

packaging ensures low package resistance improving the current handling

capability and performance of the part.

With an integrated approach, the complete switching power stage is

optimized with regards to driver and MOSFET dynamic performance,

system parasitic inductance, and Power MOSFET RDS(ON). The

FDMF8811 uses high performance PowerTrench

TM MOSFET

technology, which reduces switch ringing in converter applications. The

driver IC features low delay time and matched PWM input propagation

delays, which further enhance the performance of the part.

Features

 Compact size – 6.0 mm x7.5 mm PQFN

 High current handling: 20A



>97% system efficiency at 600W full bridge applications PSRR

value

 Wide driver power supply range: 8V to 14V

 Internal pull-down resistors for PWM inputs (HI,LI)

 3.3V/TTL compatible input thresholds

 Short PWM propagation delays

 Drive power supply Under-voltage lockout (UVLO)

 Integrated 100V Half-Bridge gate driver with 1ohm Bootstrap diode

 Low Inductance and low resistance packaging for minimal operating

lower losses

 100V PowerTrench® MOSFETs for clean switching waveforms

Typical Applications

 Telecom Half / full - Bridge DC-DC converters

 Two-Switch Forward Converters

 Intermediate Bus Converters

 Brick Converters

 High-current DC-DC Point of Load (POL) converters.
