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 R
DS(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.
