AL1783中文资料60V Three Independent PWM Channel Linear LED Driver数据手册Diodes规格书

描述 Description

The AL1783 is a three-channel linear LED driver with independent PWM dimming and current-setting controls for each channel. The device is designed to target connected, commercial, industrial, and RGB LED lighting applications. The key merits of the AL1783 are attributed to a compact solution, eBOM cost effectiveness, excellent PWM dimming performance, low standby power, ease of system implementation, and up to 60V input and LED pin operating voltage. The AL1783 is available in the TSSOP-16EP package to minimize PCB space and external component count.

简介

AL1783属于集成电路（IC）的LED驱动器。由制造生产的AL1783LED 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。
