NUD4011数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The Constant Current Regulator & LED Driver is designed to replace discrete solutions for driving LEDs in AC/DC high voltage applications (up to 200 V). An external resistor allows the circuit designer to set the drive current for different LED arrays. This discrete integration technology eliminates individual components by combining them into a single package, which results in a significant reduction of both system cost and board space. This Constant Current Regulator & LED Driver is a small surface mount package SO-8.

特性 Features

• Supplies Constant LED Current for Varying Input Voltages.
• External Resistor Allows Designer to Set Current - up to 70 mA.

应用 Application

• Portables:For Battery Back-up Applications and Simple Ni-CAD Battery Charging.
• Industrial:General Lighting Applications and Small Appliances.
• Automotive:Tail Lights, Directional Lights, Back-up Light, and Dome Light.

简介

NUD4011属于集成电路（IC）的LED驱动器。由制造生产的NUD4011LED 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。
