This is a FDMF6704 DrMOS module produced by Fairchild Semiconductor Corporation. The module uses a 6 mm x 6 mm MLP package and has ultra-compact size, high performance, and high frequency.
The FDMF6704 is an XS™ DrMOS module from Fairchild Semiconductor designed for high current, high frequency synchronous buck DC-DC applications. It integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced 6 mm x 6 mm MLP package. The device utilizes Fairchild's PowerTrench™ 5 technology to reduce ringing and eliminate the need for snubber circuits in many applications.

The SMOD# pin controls Skip Mode; when pulled low, the low-side FET is turned off to improve light load efficiency.
The DISB# pin disables FET switching when held low, allowing individual phase control in multiphase designs.
No, the PowerTrench™ 5 technology can eliminate the need for a snubber circuit in buck converter applications.
