The Xtra Small High Performance, High Frequency DrMOS Module
General Description
The XS
TM
DrMOS family is Fairchild鈥檚 next-generation fully-
optimized ultra-compact integrated MOSFET plus driver power
stage solution for high current, high frequency synchronous
buck DC-DC applications. The FDMF6704A DrMOS integrates
a driver IC, two power MOSFETs and a bootstrap Schottky
diode into a thermally enhanced 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 R
DS(ON)
. This
greatly reduces the package parasitics and layout challenges
associated with conventional discrete solutions. The driver IC
incorporates advanced features such as SMOD. A 5 V gate
drive and an improved PCB interface [Low Side MOSFET
exposed pad] ensure higher performance. This product meets
the Intel 6 mm x 6 mm DrMOS pinout.
Features
Ultra- compact thermally enhanced 6 mm x 6 mm MLP
package 84 % smaller than conventional discrete solutions.
Synchronous driver plus FET multichip module.
High current handling of 35 A.
Over 93 % peak efficiency.
Logic level PWM input.
Fairchild's PowerTrench
廬
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
in the low side MOSFET.
Integrated bootstrap Schottky diode.
Adaptive gate drive timing for shoot-through protection.
Driver output disable function [DISB# pin].
Undervoltage lockout (UVLO).
Fairchild Green Packaging and RoHS
compliant. Low profile SMD package.
Applications
Compact blade servers V-core, non V-core and VTT DC-DC
converters.
Desktop computers V-core, non V-core and VTT DC-DC
converters.
Workstations V-core, non V-core and VTT DC-DC
converters.
