Additional PFC-Ready Function (FL7930C Only)  
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.  
Input-Voltage-Absent-Detection Circuit  
Maximum Switching Frequency Limitation  
Internal Soft-Start with Overshoot Prevention  
Internal Total Harmonic Distortion (THD) Optimizer  
Precise Adjustable Output Over-Voltage Protection  
Additional OVP Detection Pin (FL7930B Only)  
Open-Feedback Protection and Disable Function  
Zero-Current Detector  
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.  
150µs Internal Startup Timer  
MOSFET Over-Current Protection (OCP)  
Under-Voltage Lockout with 3.5V Hysteresis  
Low Startup and Operating Current  
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).
