Product data sheet
1. General description
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.
2. Features and benefits
Compact solution with a small form factor and a low component count Ease of integration Primary side sensing (no optocoupler required) True current source behavior:
LED current independent of mains
voltage, LED
