Overview
The FDMF6824A, produced by onsemi, is an integrated Driver & MOSFET module belonging to the XS™ DrMOS family. This module integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced, ultra-compact 6x6mm PQFN package. It is designed for high-current, high-frequency synchronous buck DC-DC applications, optimizing the complete switching power stage for dynamic performance, system inductance, and power MOSFET RDS(ON). The FDMF6824A utilizes ON Semiconductor's high-performance PowerTrench® MOSFET technology, which reduces switch ringing and eliminates the need for snubber circuits in most buck converter applications.
