PT4204 Datasheet (PowTech) - Primary Side CC Regulator

PT4204, Primary Side CC Regulator

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.
