FL7930 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 pares 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...
