Output disable for lost phase shutdown
Low profile SMD package
RoHS Compliant
General Description
The FDMF6700 is a fully optimized integrated 12V Driver plus
MOSFET power stage solution for high current synchronous
buck DC-DC applications. The device integrates a driver IC and
two Power MOSFETs into a space saving, 6mm x 6mm, 40-pin
Power66™ package. Fairchild Semiconductor’s integrated
approach optimizes the complete switching power stage with
regards to driver to FET dynamic performance, system
inductance and overall solution ON resistance. Package
parasitics and problematical layouts associated with
conventional discrete solutions are greatly reduced. This
integrated approach results in significant board space saving,
therefore maximizing footprint power density. This solution is
based on the Intel™ DrMOS specification.
Applications
Desktop and server VR11.x V-core and non V-core buck
converters.
CPU/GPU power train in game consoles and high end
desktop systems.
High-current DC-DC Point of Load (POL) converters
Networking and telecom microprocessor voltage regulators
Small form factor voltage regulator modules
