Description
The FL7930 is an active Power Factor Correction (PFC)
controller for low-to high-power lumens 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.
FL7930 provides over-voltage, open-feedback, over-
current, input-voltage-absent detection, and under-
voltage lockout protections. The FL7930 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.
The FL3930B provides an additional OVP pin that can
be used to shut down the boost power stage when
output voltage exceeds OVP level due to damaged
resistors connected at the INV pin. The FL7930C
provides a PFC-ready pin can be used to trigger other
power stages when PFC output voltage reaches the
proper level (with hysteresis).
