Description
The SPS family is Fairchild’s fully optimized, ultra-
compact, integrated MOSFET plus driver power stage
solution for high-current, high-frequency, synchronous
buck, DC-DC applications. The FDMF3039 integrates a
driver IC with a bootstrap Schottky diode and two power
MOSFETs into a thermally enhanced, ultra-compact
3.5 mm x 4.5 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 Fairchild'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
FDMF3039 supports diode emulation (using FCCM pin)
for improved light-load efficiency. The FDMF3039 also
provides a 3-state 5 V PWM input for compatibility with
a wide range of PWM controllers.
Applications
Notebook, Tablet PC and Ultrabook
Servers and Workstations, V-Core and Non-V-Core
