FDMF3035
Integrated MOSFET driver and power stage module.
Product Description
The SPS family is onsemi’s next−generation, fully optimized,
ultra−compact, integrated MOSFET plus driver power stage solution
for high−current, high−frequency, synchronous buck, DC−DC
applications. The FDMF3035 integrates a driver IC with a bootstrap
Schottky diode and two power MOSFETs into a thermally enhanced,
ultra−compact 5 mm x 5 mm package.
With an integrated approach, the SPS switching power stage is
optimized for driver and MOSFET dynamic performance, minimized
system inductance, and power MOSFET RDS(ON). The SPS family
uses onsemi’s high−performance POWERTRENCH® MOSFET
technology, which reduces switch ringing, eliminating the need for a
snubber circuit in most buck converter applications.
A driver IC with reduced dead times and propagation delays further
enhances the performance. The FDMF3035 supports diode emulation
(using FCCM pin) for improved light−load efficiency. The
FDMF3035 also provides a 3−state 5 V PWM input for compatibility
with a wide range of PWM controllers.
