AR2003FV Overview
The AR2003FV is Active/Synchronous Rectification Controller, providing output voltage from 4.5V to 21V. Using internal drain-tosource voltage sensing, the AR2003FV is ideal for Fly-back, LLCresonant and other power supply architectures. It has SFB pin that can eliminate the external feedback resistor when target output voltage is 5V or 12V.
