  • Typical Application for CL320, 3-Channel 20mA Linear LED Driver. The CL320 is designed to drive 3 strings of LEDs at a constant current of 20mA. Other drivers with currents in the range of 20 - 30mA are available. The drive current is fixed, with a ±6% tolerance over a VOUT range of 4.0 - 15V. Separate enable pins for each channel allow for PWM dimming, 3-step linear dimming, or individual disconnection of faulty LED strings
