功能和優勢
- ■ 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
應用
- ■ SSL21151 is suitable for applications up to 5 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)
