The LTC3370 is a highly flexible multioutput power supply IC. The device includes four synchronous buck converters, configured to share eight 1A power stages, each of which is powered from independent 2.25V to 5.5V inputs.The DC/DCs are assigned to one of eight power configurations via pin programmable C1-C3 pins. The common buck switching frequency may be programmed with an external resistor, synchronized to an external oscillator, or set to a default internal 2MHz clock.The operating mode for all DC/DCs may be programmed via the PLL/MODE pin for Burst Mode or forced continuous mode operation.

Demonstration circuit DC2343A is a complete system level solution for a nanopower 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 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. By adding the software correction the first order known errors are compensated for over the operating range and the resultant coulomb count is accurate to within 3%.

Demonstration circuit 2350B features the LTC6813-1, 18-channel battery-stack monitor. Multiple boards can be linked through a 2-wire isolated serial interface (isoSPI™) to monitor a long series of cells in a stack. The DC2350B demo board also features reversible isoSPI enabling a redundant communication path. The PCB, components, and DuraClik connectors are optimized for low EMI susceptibility and emissions. The DC2350B can communicate to a PC by connecting a DC2792B dual master isoSPI together with DC2026C Linduino® One. The DC2026 must be loaded with the appropriate program (called a sketch) to control the battery-stack monitor IC and receive data through a USB serial port. The DC2026 provides a standard SPI interface which can be translated to isoSPI and then connected to a DC2350B isoSPI port (J4 or J5 connector). The DC2792B companion board provides two SPI-isoSPI channels for reversible operation.
