The FDMF6704A is a high performance, high frequency DrMOS module with a compact 6mm x 6mm MLP package. It offers high power density and efficiency and is ideal for high frequency synchronous buck DC-DC applications.
The FDMF6704A is an ultra-compact, integrated MOSFET plus driver power stage solution designed for high current and high frequency synchronous buck DC-DC applications. It integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a 6 mm x 6 mm MLP package, offering significant space savings compared to conventional discrete solutions.
The module utilizes Fairchild's PowerTrench 5 MOSFET technology and SyncFET technology to ensure clean voltage waveforms with reduced ringing, often eliminating the need for external snubber circuits. It is optimized for switching frequencies up to 1 MHz and includes features such as Skip Mode (SMOD) for improved light load efficiency and adaptive gate drive timing for shoot-through protection.
