PT4204 is targeted to sub-5W LED lighting applications. It is designed for the flyback topology, and regulates output current without the secondary feedback loop. A 600V power switch is integrated into PT4204 witch is helpful for reducing the circuit board dimension and system total cost. Accurate CC (constant current) regulation can be achieved with built .
