Description
The SPS family is Fairchild’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
FDMF3037 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 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
FDMF3037 supports diode emulation (using FCCM pin)
for improved light-load efficiency. The FDMF3037 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
DC-DC Converters
Desktop and All-in-One Computers, V-Core and
Non-V-Core DC-DC Converters
High-Current DC-DC Point-of-Load Converters
Small Form-Factor Voltage Regulator Modules
