PT4203 is targeted to below 10W LED lighting applications. It is designed for the flyback topology, and regulates output current without the secondary feedback loop. The PT4203 provide accurate CC (constant current) regulation with built in compensation circuitry. Integrated line and primary inductance compensation ensures output current free of line voltag.
