™
The XS DrMOS family is ON Semiconductor’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 FDMF6821C integrates a driver IC,
two power MOSFETs, and a bootstrap Schottky diode into a thermally
enhanced, ultra−compact 6x6 mm package.
With an integrated approach, the complete switching power stage is
optimized with regard to driver and MOSFET dynamic performance,

system inductance, and power MOSFET R
. XS DrMOS uses
DS(ON)
®
ON Semiconductor’s high−performance POWERTRENCH
MOSFET technology, which dramatically reduces switch ringing,
eliminating the need for snubber circuit in most buck converter
applications.
MARKING DIAGRAM
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 FDMF6821C also
incorporates a Skip Mode (SMOD#) for improved light−load
efficiency. The FDMF6821C also provides a 3−state 3.3 V PWM input
for compatibility with a wide range of PWM controllers.
