NCP4307 Secondary Synchronous Rectification Drivers

onsemi’s secondary side rectification drivers are ideal for high-efficiency SMPS topologies

Image of onsemi's NCP4307 Secondary Synchronous Rectification Driversonsemi’s NCP4307 series high-performance drivers are tailored to control a synchronous rectification MOSFET in switch mode power supplies. These high-performance drivers are versatile; they can be used in various topologies such as DCM or CCM flyback, quasi-resonant flyback, active clamp flyback, and forward. Self-supply capability and dual VCC pin option optimize designs for wide VOUT range applications, such as USB PD, and can be configured for high-side or low-side operations.

Features
  • Precise true secondary zero current detection
  • Dual supply pins
  • Self-supply
  • Positive dv/dt detection
  • Light load detection
Applications
  • USB PD
  • High-density SMPS
