The FDMF6820A is an ultra-compact, high-performance, high-frequency DrMOS module featuring 72% space savings, fully optimized system efficiency, clean switching waveforms with minimal ringing and high-current handling.
The document describes the Fairchild FDMF6820A, an extra-small, high-frequency DrMOS module 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 40-lead, clipbond PQFN package measuring 6.0mm x 6.0mm.
Key features include over 93% peak efficiency, high-current handling up to 60A, and the use of Fairchild PowerTrench technology for clean switching waveforms with minimal ringing. The module supports frequencies up to 1MHz and includes protection features such as thermal warning flags, under-voltage lockout (UVLO), and adaptive gate drive timing for shoot-through protection.
