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

ï® Compact solution with a small form factor and a low component count

ï® Ease of integration

ï® Primary side sensing (no optocoupler required)

ï® True current source behavior:

ïµ LED current independent of mains voltage, LED voltage and temperature variation

ïµ LED current accuracy (10 %)

ïµ Line regulation: ï±3 % at 230 V ï±10 %

ïµ Load regulation: ï±3 % between 0.5 ï´ Umax and 0.85 ï´ Umax

ï® Efficiency up to 86 % depending on the application

ï® Power Factor 0.6 or ~0.9 using valley fill

ï® Low ripple current < 1 %

ï® Internal protections:

ïµ OverTemperature Protection (OTP)

ïµ LED short protection (IOUT (0 V â V maximum) at a constant level)

ïµ LED open protection

ïµ UnderVoltage LockOut (UVLO)

ï® Internal supply voltage generation enabling start-up from the rectified mains voltage

ï® SO7 package
