Description

The AR2003 is Active/Synchronous Rectification Controller, providing output voltage from 4.5V to 20V. Using internal drain-to-source voltage sensing, the AR2003 is ideal for Flyback, LLC-resonant and other power supply architectures. By using SFB pin, output voltage can be changed dynamically by changing the Output Voltage Control pin’s level.

 

Application
  • AC/DC Battery Charger
  • Flyback Conversion
  • PC Power Supply
  • SMPS
Features
  • Wide working range 5~20V
  • Optimized for Resonant operation up to 600kHz
  • Suitable for DCM, CCM, CrCM in Fly-back operation
  • Minimum on-time and off-time to reduce turn-on/off oscillations
  • Light Load Detection (LLD) for sleep mode
  • Drain voltage rating of 200V
  • Low component count
  • Low Quiescent Current at 36µA (typ.)
