Fairchild FDMF6705 Extra-Small High-Performance DrMOS Module Datasheet
The FDMF6705 is a high-performance, extra-small DrMOS module 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 6x6mm PQFN package.
Key features include over 93% peak efficiency, the ability to handle up to 40A at 12V input, and clean switching waveforms with minimal ringing due to Fairchild PowerTrench technology. The module incorporates adaptive gate drive timing for shoot-through protection, a thermal warning flag, and skip-mode operation for improved light-load efficiency.
