NUD4001DR2集成電路（IC）的LED驅(qū)動器規(guī)格書PDF中文資料

NUD4001DR2屬于集成電路（IC）的LED驅(qū)動器。由安森美半導(dǎo)體公司制造生產(chǎn)的NUD4001DR2LED 驅(qū)動器器件屬于 LED 驅(qū)動器電源管理集成電路 (PMIC) 系列，可通過標稱固定電壓的電源為負載（通常為發(fā)光二極管）提供電流，并且電流可控。它與用于電壓調(diào)節(jié)的類似產(chǎn)品的主要區(qū)別在于，這類器件提供較低的反饋電壓（以提高系統(tǒng)能效），而且通?？蓪ζ骷ぷ鼽c進行外部控制，可在照明應(yīng)用中用于實現(xiàn)調(diào)光功能。

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).
