LT3964集成電路（IC）的LED驅(qū)動器規(guī)格書PDF中文資料

LT3964屬于集成電路（IC）的LED驅(qū)動器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的LT3964LED 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。

DESCRIPTION

The LT?3960 is a robust high speed transceiver that

extends a single-master I2C bus through harsh or noisy

environments at up to 400kbps using the CAN-physical

layer. One LT3960 sits near the I2C master, creating from

SCL and SDA equivalent differential buses (I2CAN) on

two twisted pairs. At the other end of the twisted pairs, a

second LT3960 recreates the I2C bus locally for any slave

I2C devices. A built-in 3.3V LDO powers both the I2C and

I2CAN buses from a single input supply from 4V to 60V.

Alternatively, the LT3960 can be powered directly from a

3.3V or 5V supply.
