Typical Application for CL325, 3-Channel, 25mA Linear LED Driver, Lowering CL325 Power Dissipation: Dropping Resistor. The CL325 is designed to drive 3 strings of LEDs at a constant current of 25mA. 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 - 15V. Separate enable pins for each channel allow for PWM dimming, 3-step linear dimming, or individual disconnection of faulty LED strings
