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

TopologyBuck-Boost Converter
Input voltage17-54 V
Output 134 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

Features

  • VIN Range: 6V to 80V
  • VB AT Range: 1.3V to 80V
  • Single Inductor Allows VIN Above, Below, or Equal to VB AT
  • Automatic MPPT for Solar Powered Charging
  • Automatic Temperature CompensationnI2C Telemetry and Configuration
  • Internal EEPROM for Configuration Storage
  • Operation from Solar Panel or DC Supply
  • Four Integrated Feedback Loops
  • Synchronizable Fixed Frequency: 100kHz to 400kHz
  • 64-Lead (7mm × 11mm × 0.75mm) QFN Package

Typical applications

  • The DC2703A-A-KIT demo board is configured for 17Vto 54V input voltage range and the power source can be a solar panel with 36 to 72 cells (up to 200W)
  • High Voltage Buck-Boost Battery Charge Controller with Maximum Power Point Tracking (MPPT) and I2C
