Overview

PT4203 Primary Side CC Regulator for LED driver DESCRIPTION： 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 voltage and primary inductance variations.
Complete protection functions have been integrated allows PT4203 to protect against all fault conditions including cycle by cycle current limit, output open/short circuit, line under-voltage, and over temperature shut down.
PT4203 is available...
