NCP4304ADR2G產(chǎn)品概述

The NCP4304A/B is a full featured controller and driver tailored to control synchronous rectification circuitry in switch mode power supplies. Due to its versatility, it can be used in various topologies such as flyback, forward and Half Bridge Resonant LLC.
The combination of externally adjustable minimum on and off times helps to fight the ringing induced by the PCB layout and other parasitic elements. Therefore, a reliable and noise less operation of the SR system is insured.
The extremely low turn off delay time, high sink current capability of the driver and automatic package parasitic inductance compensation system allow to maximize synchronous rectification MOSFET conduction time that enables further increase of SMPS efficiency.
Finally, a wide operating VCC range combined with two versions of driver voltage clamp eases implementation of the SR system in 24 V output applications.

Features:
  • Self-Contained Control of Synchronous Rectifier in CCM, DCM and QR Flyback Applications
  • Precise True Secondary Zero Current Detection with Adjustable Threshold
  • Automatic Parasitic Inductance Compensation Input
  • Typically 40 ns Turn Off Delay from Current Sense Input to Driver
