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)
