SC600BIMSTRT集成電路（IC）的LED驅動器規(guī)格書PDF中文資料

SC600BIMSTRT屬于集成電路（IC）的LED驅動器。由Semtech Corporation制造生產的SC600BIMSTRTLED 驅動器器件屬于 LED 驅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。它與用于電壓調節(jié)的類似產品的主要區(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，可在照明應用中用于實現(xiàn)調光功能。

Description

The SC600 is a versatile charge pump designed for use in battery operated power supply applications. The wide input range is matched for Li-Ion battery applications. mAhxLifeTM LED Drivers feature a fractional charge pump implementation with efficiency comparable to a switching regulator without costly inductors. Only two tiny ceramic capacitors are required, and the inductorless implementation provides a reduced-EMI solution. Patented low noise mode switching circuitry and constant output current allow the use of extremely small input and output capacitors.
