SSL2115X Low-cost non-dimmable LED driver IC Rev. 2 7 June 2012 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 voltage and temperature variation LED current accuracy (10 %) Line regulation: 3 % at 230 V 10 % Load regulation: 3 % between 0.5 U and 0.85 U max max Efficiency up to 86 % depending on the application Power Factor 0.6 or ~0.9 using valley fill Low ripple current < 1 % Internal protections: OverTemperature Protection (OTP) LED short protection (I (0 V V maximum) at a constant level) OUT LED open protection UnderVoltage LockOut (UVLO) Internal supply voltage generation enabling start-up from the rectified mains voltage SO7 packageSSL2115X NXP Semiconductors Low-cost non-dimmable LED driver IC 3. Applications SSL21151 is suitable for applications up to 5 W mains power SSL21153 is suitable for applications up to 10 W mains power SSL retrofit lamps (small-sized light bulbs or LED spots) LED module, mains AC/DC converter (down-lights) LED strings (retail displays) 4.
