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
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
