Beschreibung

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.

Merkmale

  •  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)
  •  Internal supply voltage generation enabling start-up from the rectified mains voltage
  •  Compatible with wall switches with built-in indication light during standby
  •  SO14 package
