NUD4001屬于開發(fā)板套件編程器的評估板-LED驅(qū)動器。由安森美半導(dǎo)體公司制造生產(chǎn)的NUD4001評估板 - LED 驅(qū)動器LED 驅(qū)動器評估板是帶有元器件的電路板，用于提供特定電路或器件的工作實例。該系列評估板提供一個 LED 驅(qū)動器實例，用于可調(diào)節(jié)閃爍、模擬亮度、背光、雙極開關(guān)、升壓轉(zhuǎn)換器、亮度控制、相機閃光燈、可調(diào)光、恒流和 RGB 控制，以及更多其他應(yīng)用。

This device is designed to replace discrete solutions for driving LEDs in low voltage AC?DC applications 5.0 V, 12 V or 24 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. The device is a small surface mount package (SO–8).
