AN-8026 / FEB301_FAN9611 / FAN9612 User Guide is the user guide for FAN9611 / FAN9612 400W evaluation board for interleaved boundary-conduction mode power factor corrected supply.
This document serves as a user guide for the FAN9611/FAN9612 400W evaluation board (FEB-301), designed for interleaved boundary-conduction mode power factor corrected supplies. The guide supports the FAN9611/FAN9612 controllers, which operate two parallel-connected boost power trains 180° out of phase to extend practical power levels beyond 800W. The board is rated for 400W (400V/1A) and maintains efficiencies above 95% at low-line and high-line conditions.
