General Description
The FDMF8704 is a fully optimized integrated 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, MLP 8x8, 56-pin
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.
