Overview
Critical Conduction Mode PFC Controller FAN7930B Description The FAN7930B 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 the voltage−mode CRM PFC controller does not need rectified AC line voltage information, it saves the power loss of an input voltage sensing network necessary for a current−mode CRM PFC controller.
FAN7930B provides over−voltage protection (OVP), open−feedback protection, over−current protection (OCP), input−voltage−absent detection, and under−voltage ...
