1. General description
2. Features and benefits
The SSL2115X is a low-cost non-dimmable LED driver IC. It is designed to drive LEDs in
isolated flyback or non-isolated buck-boost topologies. The device includes a high-voltage
power switch and a circuit enabling start-up directly from the rectified mains voltage. It has
a good controlled output current.
