TPS92664QPHPRQ1集成电路（IC）的LED驱动器规格书PDF中文资料

TPS92664QPHPRQ1属于集成电路（IC）的LED驱动器。由德州仪器制造生产的TPS92664QPHPRQ1LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。

3 Description

The TPS92664 LED matrix manager device enables

fully dynamic adaptive lighting solutions by providing

individual pixel-level LED control. The device includes

four sub-strings of four series connected integrated

switches for bypassing individual LEDs. The individual

sub-strings allow the device to accept either single or

multiple current sources.

The TPS92664 features an internal oscillator.

The internal oscillator can be shared to other

system devices through the internal low noise

LVDS transmitter and receiver blocks. The multidrop,

universal, asynchronous, receiver transmitter

(UART) serial interface is compatible with TPS92665,

TPS92667, TPS92662x and TPS92663x devices.

The internal EEPROM can store system defaults as

well as calibration and lighting module data. An onboard

ADC with multiplexed inputs samples all LED

channels as well as IC die temperature and an LED

current sense. The ADC also samples dedicated ADC

inputs for use with system temperature compensation,

LED binning and coding.

The TPS92664 incorporates registers for

programming phase shift and pulse width of each

individual LED in the string and for reporting LED

open, short faults and functional parameters.
