CL325、3 通道、25mA 线性 LED 驱动器的典型应用,降低 CL325 功耗:
齐纳二极管。 CL325 设计用于以 25mA 的
恒定电流驱动 3 串 LED。还提供电流在 20 - 30mA 范围内的其他驱动器。驱动电流是固定的,在 4 - 15V 的 VOUT 范围内具有 ±6% 的容差。每个通道的独立使能引脚可实现 PWM 调光、3 步线性调光或单独断开故障 LED 灯串

Typical Application for CL325, 3-Channel, 25mA Linear LED Driver, Lowering CL325 Power Dissipation: Zener Diode. 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
