产品描述

The SSL2115x is a series of low cost LED driver IC's. It is designed to drive LED devices typically in flyback configurations. The devices include a high-voltage power switch and a circuit enabling start-up directly from the rectified mains voltage. It has a good controlled output current.

产品特性和优势

Suitable for applications up to 5 W (SSL21151) or 10 W (SSL21153) mains power
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

产品应用

SSL retrofit lamps (small-sized light bulbs or LED spots)
LED module, mains AC/DC converter (down-lights)
LED strings (retail displays)
