NCL31010中文资料PoE Interface LED Driver, Visible Light Communication capable数据手册ONSEMI规格书

描述 Description

The NCL31010 comprises all elements needed to design a connected and managed lighting system via Power-over-Ethernet, including capabilities for Visible Light Communication and Indoor Positioning. Certified to the IEEE802.3bt/at/af standards, over 90W of system power can be delivered. The NCL31010 incorporates a high efficiency buck LED driver that supports both high-bandwidth analog and PWM dimming down to zero current.  Two auxiliary DC-DC converters are included to power for example the system microcontroller and  sensors.  High accuracy metrology and diagnostics are included to measure input and output current and voltage, LED or system temperature, and DC-DC voltages and currents. Additional devices in the NCL31000 family are:

NCL31000 – non-PoE version to accommodate other communication standards
NCL31001 - a reduced-feature version to enable multi-channel solutions

简介

NCL31010属于集成电路（IC）的LED驱动器。由制造生产的NCL31010LED 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。
