DC2069A

Demonstration circuit 2069A features LT®8490, a high performance buck-boost converter that implements an MPPT function and flexible charging profiles suitable for most battery types such as flooded and sealed lead acid batteries and Lithium-Ion batteries and can operate from input voltages above below or equal to the battery voltage. The demo board is configured for a 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. Two input connectors are provided. An LTC4359 ideal diode controller protects the DC power supply output from being back fed from the solar panel.
