Description
The FAN7930 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.
FAN7930 provides over-voltage protection, open feedback protection, over-
current protection, input voltage-absent detection, and under-voltage lockout
protection. The PFC-ready pin can be used to trigger other power stages when
PFC output voltage reaches the proper level with hysteresis. The FAN7930 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.
