ETA8003 - Secondary-Side Synchronous Rectifier Driver

Description

The ETA8003 is a high performance and highly integrated secondary side synchronous rectification controller in switch mode power supply system.

It drivers a much lower voltage drop N-channel MOSFET to replaces the output rectifier diode in a flyback topology.

Features

  • Supports CCM, DCM and QR Operation Mode.
  • Suitable for 10-200KHz switching frequency.
  • Externally adjustable minimum on time.
  • Up to 120V VD pin high voltage.
  • Power savings in standby mode or light load.
  • Self-powered technology without extra Winding.
  • Fast turns on/off.
  • Supports both High/Low Side Rectification.
  • Available in a Standard SOT23-6 Package.
  • RoHS Compliant.

ETA8003 Secondary-Side Synchronous Rectifier Driver DESCRIPTION The ETA8003 is a high performance and highly integrated secondary side synchronous rectification controller in switch mode power supply system. It drivers a much lower voltage drop N-channel MOSFET to replaces the output rectifier diode in a flyback topology. This can reduce heat dissipation, improve system efficiency, and simplify thermal design. It can effectively help power system meet the latest DOE2.0 standard average efficiency requirement. Very low quiescent current in standby mode ensures lower system standby power. The ETA8003 is suitable for flyback converter operating in continuous conduction mode (CCM), discontinuous conduction mode (DCM), and quasi-resonant mode.
