NCL30170中文资料用于功率因数校正和精确恒定电流调节的直接交流驱动 LED 驱动器数据手册ONSEMI规格书

描述 Description

The NCL30170 is a linear regulating constant current LED controller in smart lighting and phase-cut dimming application. The controller manages multiple series LED current in ON semiconductor’s proprietary auto-commutation topology with high CC regulation accuracy and superior performance in PF and THD.
The device provides wide analog dimming range with linear dimming curve and low current consumption in the standby mode. In phase-cut dimming application, input current shape modulation provides both good PF and excellent dimmer compatibility. Self-biasing high-voltage regulator supplies stable IC bias voltage with fast startup time. The NCL30170 has several protections such as thermal shutdown, input over voltage protection, sensing resistor short protection and LED over current limit for high system reliability.

简介

NCL30170属于集成电路（IC）的LED驱动器。由制造生产的NCL30170LED 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。
