PT4213 - PowTech

PT4213 Primary Side CC Controller

The PT4213 is a primary side regulated constant current controller, which is designed for LED lighting applications. The device is optimized for high performance and cost-effective applications. With Powtech’s proprietary constant current compensation technique accurate constant current regulation is achieved without the need of a secondary feedback circuitr.
