Overview: DATA SHEET www.onsemi.com Extra-Small, High-Performance, High-Frequency DrMOS Module PQFN40 6x6, 0.5P CASE 483AN FDMF6820A
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.
With an integrated approach, the complete switching power stage is optimized with regard to driver and MOSFET dynamic performance, system inductance, and power MOSFET RDS(ON). XS DrMOS uses 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.
