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

FDMF301155 integrates a driver IC with a bootstrap

Schottky diode and two power MOSFETs into a

thermally

enhanced,

ultra-compact

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

FDMF301155 supports diode emulation (using FCCM

pin) for improved light-load efficiency. The FDMF301155

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
