AL5890中文资料400V Linear Constant Current LED Driver数据手册Diodes规格书

描述 Description

The AL5890 is a 500V linear constant current LED driver and it provides a cost-effective two pin solution. It has good temperature stability and the current accuracy of ±10% regulated over a wide voltage and temperature range. The AL5890 comes in various fixed output current options removing the need for external current setting resistors and creating a simple driver solution for the series of LEDs. The AL5890 supports both the high-side and low-side driving of LED chains.The AL5890 turns on when the voltage between IN and OUT is greater than 7V. Long LED chain application up to 500V operating voltage subject to package thermal limitation.The AL5890 is available in thermally robust PDI123 package.

简介

AL5890属于集成电路（IC）的LED驱动器。由Diodes制造生产的AL5890LED 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。
