SC4509規(guī)格書詳情
SC4509屬于集成電路(IC)的LED驅(qū)動器。由Semtech Corporation制造生產(chǎn)的SC4509LED 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(biāo)稱固定電壓的電源為負(fù)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(jìn)行外部控制,可在照明應(yīng)用中用于實現(xiàn)調(diào)光功能。
