Fairchild FLS3217 PFC PSR Offline LED Drivers

Fairchild's FLS3217 PFC PSR Offline LED Drivers are a highly integrated PWM controller with power MOSFET that provides features to enhance the performance of low-power flyback converters. The proprietary topology enables simplified design for LED lighting applications. By using the single-stage topology with primary-side regulation, an LED lighting board can be implemented with the few external components and minimized cost; requiring no input bulk capacitor or feedback circuitry.
