Product Overview

The DC2069A is a 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. This allows, for example, that a 24VDC supply is plugged in while a solar panel with higher voltage is being used to power the circuit.
  • On-chip logic provides automatic true power point tracking for solar powered applications
  • Simple serial interface also sends out status bytes that can be interpreted by external circuitry
