PT4213 Datasheet | PowTech

Primary Side CC Controller GENERAL DESCRIPTION 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 pensation technique accurate constant 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 primary inductance. Excellent EMI performance is achieved with frequency jittering function together with soft driving control at totem pole gate drive output. The device also Features a plete set of protection functions to protect against all fault conditions including output open/short circuit, line under-voltage, and over temperature. The PT4213 is available in an SOT23-6 package.
