DATA SHEET www.onsemi.com Single-Stage Primary-Side-Regulation PWM Controller for PFC and Phase Cut Dimmable LED Driving FL7734 Description The FL7734 is a highly integrated PWM controller with advanced Primary−Side−Regulation (PSR) technique to minimize components for low power LED lighting solutions. Using the innovative TRUECURRENT technology for tight constant−current control, it enables designs with constant−current (CC) tolerance of less than +1% in the wide line voltage range to meet stringent LED brightness requirements. FL7734 can operate with all types of phase cut dimmers. Phase cut dimming is managed smoothly by onsemi’s proprietary constant input current control and bleeding current control to achieve excellent dimmer compatibility without visible flicker.
