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 FDMF6704 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. PWM input is
Tri-State compatible. A 5 V gate drive and an improved PCB
interface [Low Side MOSFET exposed pad] ensure higher
performance. This product is compatible with the new Intel
6 mm x 6 mm DrMOS specification.
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.
Gaming Motherboards V-core, non V-core and VTT DC-DC
converters.
Gaming consoles.
High-current DC-DC Point of Load (POL) converters.
Networking and telecom microprocessor voltage regulators.
