SSL6203TW

SSL6203TW 120 V mains dimmable, 12 W linear LED driver Rev. 1 — 3 November 2014 Objective data sheet 1. General description The SSL6203TW is a monolithic high-voltage Integrated Circuit (IC) that can drive and dim three high-voltage LED strings directly from the rectified mains. The high level of integration gives a low-cost and low component count application, which is especially suitable for retrofit Solid-State Lighting (SSL). The IC operates as a linear high-voltage current source. The string current in the LEDs can easily be adjusted. A patented LED drive scheme ensures optimal LED utilization. The application can be dimmed. It also runs on a leading-edge phase cut dimmer with the integrated smart bleeder current. To guarantee correct and proper operation, the SSL6203TW incorporates many protection features. A thermally enhanced small outline package gets rid of the heat and makes integration of the whole application on the LED plate possible. 2.
