PT4227 Overview
The PT4227 is primary side constant current regulator, which is designed for high performance and cost-effective LED lighting applications. With Powtech’s proprietary constant current pensation technique accurate output current regulation is achieved without the need of a secondary feedback circuitry. Integrated primary inductance pensation circuitry provides accurate constant current operation despite variations in...
