ADI Power by Linear LT8491 | Demoboard DC2703A-A-KIT

High Voltage Buck-Boost Battery Charge Controller with Maximum Power Point Tracking (MPPT) and I2C

Overview

Topology Buck-Boost Converter
Input voltage 17-54 V
Output 1 34 V / 16.6 A

Description

The DC2703A-A-KIT contains the DC2703A (LT8491demo board) and DC1613A (USB-to-I2C controller). Together they provide a high performance buck-boost battery charger converter with an I2C interface. The LT8491 implements a maximum power point tracking (MPPT) function and flexible charging profiles, suitable for most battery types such as flooded and sealed lead acid batteries and Li-Ion batteries. A Microsoft Windows-Based GUI (Graphical User Interface) application called “simpleLT8491” is provided which can be downloaded
