NCP4305DDR2G General Description

The NCP4305DDR2G is a high-performance driver designed to efficiently control a synchronous rectification MOSFET in switch mode power supplies. With its versatile design, it can be implemented in various topologies including DCM or CCM flyback, quasi resonant flyback, forward, and half bridge resonant LLC. This driver offers externally adjustable minimum off-time and on-time blanking periods, which helps mitigate ringing caused by PCB layout and other parasitic elements. Additionally, the Self Synchronization feature ensures a reliable and noiseless operation of the SR system
