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.

Features : 

1. Integrated 120 mA (120 V (AC) mains compatible) high-voltage current sources

2. Integrated bleeder high-voltage current source

3. Integrated low voltage supply regulator

4. Two high-voltage current sources per output for optimal heat balancing

Applications : 

1. 120 V (AC) mains dimmable retrofit SSL lamps
