FDMF8705
Description
The FDMF8705 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, 8mm x 8mm, 56-pin Power88™ package. Fairchild Semiconductor’s integrated approach optimizes the plete 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™ Dr MOS specification.
