Description

This reference design is featured in solar lithium battery applications. This design: which contains an integrated switch-mode battery charge controller: provides input voltage regulation: which reduces charge current when input voltage falls below a programmed level. When the input is powered by a solar panel: the input regulation loop maintains the panel at maximum power output. This solution is also called the HPA639 A. The manual includes the  bill of materials: board layout: and schematic. The user's guide describes the features and operation of the solution.
