AL6562A中文资料Transition Mode PFC LED Controller数据手册Diodes规格书

描述 Description

The AL6562A is a current mode Power Factor Correction Controller and is designed for operating in Transition Mode. With a superior linear performance multiplier, it ensures the device operates over a wide input voltage range with superior THD (Total Harmonics Distortion). The output voltage is controlled by means of an error amplifier and a precise (1% @ TJ = +25°C) internal voltage reference.
The AL6562A is designed to meet stringent energy-saving standards with low start-up current, and can operate with low current consumption when entering stand-by mode.
OVP circuitry increases system robustness, allowing the device to withstand transient caused at start-up and during load-disconnects.

简介

AL6562A属于集成电路（IC）的LED驱动器。由制造生产的AL6562ALED 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。
