MARKING DIAGRAM
The XS DrMOS family is onsemi’s next−generation, fully optimized,
ultra−compact, integrated MOSFET plus driver power stage solution
for high−current, high− frequency, synchronous buck DC−DC
applications. The FDMF6820A integrates a driver IC, two power
MOSFETs, and a bootstrap Schottky diode into a thermally enhanced,
ultra−compact 6x6 mm package.

FDMF6820A = Device Code
onsemi’s high−performance POWERTRENCH MOSFET
technology, which dramatically reduces switch ringing, eliminating the
need for snubber circuit in most buck converter applications.
A driver IC with reduced dead times and propagation delays further
enhances the performance. A thermal warning function warns of a
potential over−temperature situation. The FDMF6820A also
incorporates a Skip Mode (SMOD#) for improved light−load efficiency.
The FDMF6820A also provides a 3−state 3.3 V PWM input for
compatibility with a wide range of PWM controllers.
