Description
The FAN7930C 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.
FAN7930C provides over-voltage protection (OVP),
open-feedback
protection,
over-current
protection
(OCP), input-voltage-absent detection, and under-
voltage lockout protection (UVLO). The PFC-ready pin
can be used to trigger other power stages when PFC
output voltage reaches the proper level with hysteresis.
The FAN7930C 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.
