CL330_Typical Application

描述

Typical Application for CL330, 3-Channel, 30mA Linear LED Driver, Lowering CL330 Power Dissipation: Zener Diode. The CL320/CL325/CL330 are designed to drive three strings of LEDs at a constant current of 20 mA, 25 mA and 30 mA, respectively. The drive current is fixed, with a ±6% tolerance over a VOUT range of 4V to 15V. Separate enable pins for each channel allow for PWM dimming, three-step linear dimming or individual disconnection of faulty LED strings
