LD6802J中文资料LED lighting Output Current Ripple Suppressor for Dimmable LED Constant Current System数据手册Leadtrend规格书

描述 Description

The LD6802J is an output current ripple suppressor for LED lighting. It supports easy use at output terminal with isolation or non-isolation active PFC architecture with constant current.

The LD6802J is easy to achieve current ripple limitation with minimum output capacitance and built-in adjustable over voltage protection/ multi-level over current protection and internal clamp Zener diode could be used at wide range LED voltage application. The device is the SOT-26 package to minimize the PCB size well as component counts.
