LP5024規(guī)格書詳情
LP5024屬于集成電路(IC)的LED驅(qū)動(dòng)器。由德州儀器制造生產(chǎn)的LP5024LED 驅(qū)動(dòng)器器件屬于 LED 驅(qū)動(dòng)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(diǎn)進(jìn)行外部控制,可在照明應(yīng)用中用于實(shí)現(xiàn)調(diào)光功能。

control of each color
? 2 external hardware address pins allow connecting
up to 4 devices
? Broadcast slave address allows configuring
multiple devices simultaneously
? Auto-increment allows writing or reading
consecutive registers within one transmission
? Up to 400kHz fast-mode I2C speed
2 Applications

? Electronic smart lock
? Smoke and heat detector
? STB and DVR
? Smart router
? Handheld device
3 Description
In smart homes and other applications that use
human-machine-interaction, high-performance RGB
LED drivers are required. LED animation effects
such as flashing, breathing, and chasing greatly
improve user experience, and minimal system noise
is essential.
The LP50xx device is an 18- or 24-channel constant
current sink LED driver. The LP50xx device includes
integrated color mixing and brightness control,
and pre-configuration simplifies the software coding
process. Integrated 12-bit, 29kHz PWM generators for
each channel enable smooth, vivid color for LEDs,
and eliminate audible noise.
