The DC2703A-A demonstration board is configured for a 17V to 54V input voltage range and up to 200W power source. The LT8491 controllers can operate from input voltages above, below, or equal to the battery voltage. This DC2703A-A demonstration board output is set up for charging a 12V SLA battery with up to 16.6A charge current. The demonstration board can be modified to support much higher output voltage and also modifies a higher voltage rating output side MOSFETs and capacitors. The LT8491 EEPROM on the DC2703A-A demonstration board is programmed with the onboard resistor values to accurately read charger telemetry and status registers data.
