CL325数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

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 4.0 - 15V. Separate enable pins for each channel allow for PWM dimming, 3-step linear dimming, or individual disconnection of faulty LED strings.Over-temperature protection circuitry shuts down all 3 channels when the nominal die temperature reaches 135°C. Normal operation resumes when the die temperature drops by 30°C.The CL325 is available in the 8-Lead SOIC (w/heat slug) package and requires a single ceramic bypass capacitor which may be shared among several drivers.

简介

CL325属于集成电路（IC）的LED驱动器。由制造生产的CL325LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
