描述 Description

LITIX TM  Basic TLD2326EL  is  a  three  channel  high  side  driver  IC  with  integrated  output  stages.  It  is designed to control LEDs with a current up to 120 mA. In typical automotive applications the device is capable to drive i.e. 3 red LEDs per chain (total 9 LEDs) with a current up to 60mA, which is limited by thermal cooling aspects. The output current is controlled practically independent of load and supply voltage changes.

优势:

应用 Application

Designed for exterior LED lighting applications such as tail/brake light, turn indicator, position light, side marker,... The device is also well suited for interior LED lighting applications such as ambient lighting (e.g. RGB), interior illumination and dash board lighting.

简介

TLD2326EL属于集成电路（IC）的LED驱动器。由制造生产的TLD2326ELLED 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。
