The FDMF6704V is a high performance, high frequency DrMOS module from Fairchild Semiconductor Corporation, featuring an integrated 12 V to 5 V regulator and a 6 mm x 6 mm MLP ultra compact package. It is space-saving, EMI-reduced, and high-efficiency with high-frequency and low-noise operation.
The FDMF6704V is an ultra-compact, high-performance DrMOS module designed for high current, high frequency synchronous buck DC-DC applications. It integrates a driver IC, two power MOSFETs, a bootstrap Schottky diode, and an internal 5V gate drive LDO regulator into a thermally enhanced 6 mm x 6 mm MLP package. This integrated approach optimizes the switching power stage regarding driver and MOSFET dynamic performance, system inductance, and RDS(ON), significantly reducing package parasitics and layout challenges compared to conventional discrete solutions.
