描述 Description

LITIX TM? Basic TLD1326EL? is? a? three? channel? high? side? driver? IC? with? integrated? output? stages.? It? is designed to control LEDs with a current up to 120 mA. In typical automotive applications the device is capable to drive i.e. 3 red LEDs per chain (total 9 LEDs) with a current up to 60mA, which is limited by thermal cooling aspects. The output current is controlled practically independent of load and supply voltage changes.

簡介

TLD1326EL屬于集成電路（IC）的LED驅(qū)動器。由制造生產(chǎn)的TLD1326ELLED 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），而且通常可對器件工作點進行外部控制，可在照明應用中用于實現(xiàn)調(diào)光功能。
