LD6802J数据手册Leadtrend中文资料规格书

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.
