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. The small footpri.
of this IC are the Minimum Off Time (TOFF) and Minimum on Time (TON), these features blank the noise generated during the turn on and turn off instances of the power FET. Light load detection for improved efficiency at light and no load is implemented. Other features include Under Voltage Lock Out (UVLO), SYNC feature for CCM operation and low turn off threshold voltage for improved efficiency.
