DC2343A, Demo Board for LTC3335 nano-power Buck-Boost DC/DC with Integrated Coulomb Counter

DC2343A, Demonstration Circuit is a complete system level solution for a nano-power buck-boost DC/DC with integrated coulomb counter. The DC2343A contains a PIC16F1459 embedded processor for communication to the PC over USB and the LTC3335 via its I2C port. The GUI is capable of reading and writing all the control registers on the LTC3335 as well as displaying and resetting all its alarm registers. The firmware and software for the embedded system and the GUI are available at the LTC3335 solutions page. The DC2343A uses two analog-to-digital converter channels to sample the battery and output voltages. The voltage samples improve the functionality of the GUI and allow optimal software correction to the measured coulombs
