Abstract

Combining with the application characteristic of solar energy system and the drive characteristic of high-power lighting LED, in this article, we develop a sort of new drive control chip of solar LED lighting system, which not only can be drove by the invariable current of 350mA, but also can realize functions including the regulation of charger and discharge, preventing reverse charge, preventing over charge, preventing over discharge, and preventing reverse connection of the storage battery in the photovoltaic system.
