FDMF6704A - XS^TMDrMOS

The Xtra Small, High Performance, High Frequency DrMOS Module

Benefits

General Description

Ultra compact size - 6 mm x 6 mm MLP, 44 % space

The XS^TMDrMOS family is Fairchild’s next-generation fully-

optimized, ultra-compact, integrated MOSFET plus driver power

stage solutions for high current, high frequency synchronous

buck DC-DC applications. The FDMF6704A XS^TMDrMOS

integrates a driver IC, two power MOSFETs and a bootstrap

Schottky diode into a thermally enhanced, ultra compact 6 mm x

6 mm MLP package. With an integrated approach, the complete

switching power stage is optimized with regards to driver and

MOSFET dynamic performance, system inductance and

saving compared to conventional MLP 8 mm x 8 mm

DrMOS packages.

Fully optimized system efficiency.

Clean voltage waveforms with reduced ringing.

High frequency operation.

Features

. This greatly reduces the package parasitics and layout

package 84 % smaller than conventional discrete solutions.

DrMOS

uses

Fairchild's

high

performance

Synchronous driver plus FET multichip module.

High current handling of 35 A.

Over 93 % peak efficiency.

PowerTrench

5 MOSFET technology, which dramatically

reduces ringing in synchronous buck converter applications.

PowerTrench 5 can eliminate the need for a snubber circuit in

buck converter applications. The driver IC incorporates

advanced features such as SMOD for improved light load

efficiency. A 5 V gate drive and an improved PCB interface

optimized for a maximum low side FET exposed pad area,

ensure higher performance. This product is compatible with

the new Intel 6 mm x 6 mm DrMOS specification.

Logic level PWM input.

Fairchild's PowerTrench^®5 technology MOSFETs for clean

voltage waveforms and reduced ringing.

Optimized for high switching frequencies of up to 1 MHz.

Skip mode SMOD [low side gate turn off] input.

Fairchild SyncFET^TM[integrated Schottky diode] technology

Applications

in the low side MOSFET.

Integrated bootstrap Schottky diode.

Compact blade servers V-core, non V-core and VTT DC-DC

converters.

Adaptive gate drive timing for shoot-through protection.

Driver output disable function [DISB# pin].

Undervoltage lockout (UVLO).

Desktop computers V-core, non V-core and VTT DC-DC

converters.

Workstations V-core, non V-core and VTT DC-DC

converters.

Gaming Motherboards V-core, non V-core and VTT DC-DC

converters.

Fairchild Green Packaging and RoHS

compliant. Low profile SMD package.

Gaming consoles.

High-current DC-DC Point of Load (POL) converters.

Networking and telecom microprocessor voltage regulators.

Small form factor voltage regulator modules.
