Fairchild Semiconductor
FDMF8704V
High Efficiency / High Frequency FET plus Driver Multi-chip Module with Internal Voltage Regulator

General Description

The FDMF8704V 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.
