Single-Stage Flyback and Boundary-Mode PFC Controller for Lighting

Description The FL7930C is an active power factor correction (PFC) controller for boost PFC applications that operate in critical conduction mode (CRM). It uses a voltage-mode PWM that compares an internal ramp signal with the error amplifier output to generate a MOSFET turn-off signal. Because t
