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, open-
feedback protection, over-current protection, input-
voltage-absent detection, and under-voltage lockout
protection. The additional OVP pin can be used to shut
down the boost power stage when output voltage
exceeds OVP level due to the resistors that are
connected at INV pin are damaged. The FAN7930B can
be disabled if the INV pin voltage is lower than 0.45V
and the operating current decreases to a very low level.
Using a new variable on-time control method, THD is
lower than the conventional CRM boost PFC ICs.
