SSL21101T

SSL21101T GreenChip driver for LED lighting Rev. 3 — 7 June 2012 Product data sheet 1. General description The SSL21101T is a Switch Mode Power Supply (SMPS) driver IC. It is designed to drive LED devices typically in flyback configurations. The device includes a high-voltage power switch and a circuit enabling start-up directly from the rectified mains voltage. It has accurate control of the output current. 2. Features and benefits  Small Printed-Circuit Board (PCB) footprint and compact solution with a small form factor  Ease of integration  Low component count (complete application with about 25 components)  AC/DC offline non-dimmable LED driver from 100 V (AC) to 230 V (AC)  Primary side sensing (no optocoupler required)  True current source behavior:  LED current independent of mains voltage, LED voltage, temperature and coil variation  High LED current accuracy (3 %)  Efficiency up to 90 % depending on the application  Smart Digital Control (SDC) to deal with all kind of applications:  High-Power Factor (PF; > 0.95) and low Total Harmonic Distortion Mode (THD down to 20 %)  Small form factor (low LED current mode ripple with small electrolytic capacitors) compatible with exception clause IEC61000-3-2  Internal protections:  Short-winding protection  Internal OverTemperature Protection (OTP)  LED short protection  LED open protection  UnderVoltage LockOut (UVLO)  External temperature protection with built-in Negative Temperature Coefficient (NTC)  ...
