SSL21151T

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  Umax and 0.85  Umax  Efficiency up to 86 % depending on the application www.DataSheet.net/  Power Factor 0.6 or ~0.9 using valley fill  Low ripple current < 1 %  Internal protections:  OverTemperature Protection (OTP)  LED short protection (IOUT (0 V – V maximum) at a constant level)  LED open protection  UnderVoltage LockOut (UVLO)  Internal supply voltage generation enabling start-up from the rectified mains voltage  SO7 package Datasheet pdf - http://www.DataSheet4U.co.kr/ NXP Semiconductors SSL2115X Low-cost non-dimmable LED driver IC 3.
