Product Overview

The FL7734MX is a single-stage PWM Controller for PFC and phase cut dimmable LED driving. It 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. Phase cut dimming is managed smoothly by bleeding current control to achieve excellent dimmer compatibility without flicker. The controller can automatically detect whether there is a dimmer connection. In non dimming mode, the operating mode is set to optimize power factor and THD by enabling linear frequency control and voltage mode based on DCM. The FL7734 also provides powerful protections, such as LED open/short, sensing resistor shorted and over-temperature for high system reliability.
