Analog Devices Inc. LTC333x Demonstration Board for LTC333x Converters

Analog Devices Inc. LTC333x Demonstration Boards feature a nanopower buck-boost DC/DC emphasizing the LTC333x Converters. The DC2343A offers an integrated coulomb counter and contains a PIC16F1459 embedded processor for communication. The DC2343A uses two analog-to-digital converter channels to sample the battery and output voltages. These voltage samples improve the functionality of the GUI and allow optimal software correction to the measured coulombs.

The DC2151A is a nanopower buck-boost DC/DC with energy harvesting battery charger featuring the LTC3331. The DC2151A has a rechargeable cell battery to create a single output supply for alternative energy applications using the LTC3331. The energy harvesting power supply harvests energy from piezoelectric, solar, or magnetic sources.

The DC2048A highlights the LTC3330 and is a nanopower buck-boost DC/DC with energy harvesting battery life extender. The LTC3330 integrates a high voltage energy harvesting power supply plus a DC/DC converter powered by a primary cell battery for alternative energy applications. Powering a buck-boost converter, the primary cell input is capable of operating down to 1.8V at its input. The Analog Devices Inc. LTC333x Demonstration Boards offer a complete system solution with integrated coulomb counter (DC2343A) and energy harvesting battery chargers (DC2151A & DC2048A) featuring the LTC3335, LTC3331, and LTC3330.
