PT4230 Datasheet PDF

PowTech PT4230

The PT4230 is primary side constant current regulator, which is designed for high performance and cost-effective LED lighting applications. With Powtech’s proprietary constant current compensation technique accurate output current regulation is achieved without the need of a secondary feedback circuitry. The device integrates a high voltage power switch, an oscillator, a current sense circuit, CC control circuit.

GENERAL DESCRIPTION

Integrated primary inductance compensation 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. It also features a complete set of integrated protection functions to protect against all fault conditions including output open/short circuit, line under-voltage, and over temperature shut down. The PT4230 is available in a SOP-8 package. ORDERIN
