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 lockout protection (UVLO). 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 0.45 V and the operating current decreases
to a very low level. Using a new variable on-time control
method, total harmonic distortion (THD) is lower than in
conventional CRM boost PFC ICs.
