The SSL21153T is a low cost LED 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 a good controlled output current.

Features and benefits

  • Compact solution with a small form factor and 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 x Umax and 0.85 x Umax
  • Efficiency up to 86 % depending on the application
  • 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

Applications

  • 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)
