DC2703A-A-KIT is a LT8491 high voltage buck-boost battery charge controller with Maximum Power Point Tracking (MPPT) and I2C demonstration board. The DC2703A-A-KIT contains the DC2703A (LT®8491 demo 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 MPPT function and flexible charging profiles, suitable for most battery types. The DC2703A-A-KIT board is configured for 17V to 54V input voltage range and the power source can be a solar panel with 36 to 72 cells (up to 200W) or a DC voltage source. The LT8491 converter can operate from input voltages above, below or equal to the battery voltage. The DC2703A-A-KIT board output is set up for charging a 12V SLA battery with up to 16.6A charge current. The DC2703A-A-KIT board can be modified to support much higher output voltage with modifications including higher voltage rating output side MOSFETs and capacitors.
