Overview

PT4204 Primary Side CC Regulator for LED driver DESCRIPTION： 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 in compensation circuitry.
Integrated line and primary inductance compensation ensures output current free of line voltage and primary inductance variations.
Complete protection functions have been integrated allows PT4204 to protect against all fault conditions including cycle b...
