Additional OVP Detection Pin  
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.  
Input Voltage Absent Detection Circuit  
Maximum Switching Frequency Limitation  
Internal Soft-Start and Overshoot-less Control  
Internal Total Harmonic Distortion (THD) Optimizer  
Precise Adjustable Output Over-Voltage Protection  
Open-Feedback Protection and Disable Function  
Zero Current Detector  
FAN7930B provides over-voltage protection, open-  
feedback protection, over-current protection, input-  
voltage-absent detection, and under-voltage lockout  
protection. 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 0.45V  
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.
