FL7930B − Single-Stage Flyback and Boundary Mode PFC Controller for Lighting

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 FL7930B 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).
