SSL6203TW Overview
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 ponent count application, which is especially suitable for retrofit Solid-State Lighting (SSL). The IC operates as a linear high-voltage current source.
