Fairchild FL7733 Primary-Side-Regulated LED Driver
Fairchild's FL7733 Primary-Side-Regulated LED Driver is a highly integrated PWM controller with advanced Primary-Side Regulation (PSR) technique that provides features to enhance the performance of low-to-mid-power LED lighting converters. The FL7733 LED driver is designed with minimum system components while LED current is accurately controlled by Fairchild's TRUECURRENT® technique and improved feedback loop control. Constant Current (CC) tolerance less that +/-1% over the universal line voltage range meets the requirement of highly reliable LED brightness management. The FL7733 provides powerful protections, such as LED short/open, output diode short, sensing resistor short / open, and over-temperature for high system reliability.
