FDMF3035
Smart Power Stage (SPS)
Module
Description
The SPS family is ON Semiconductor’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 ON Semiconductor’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.
