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.

Demonstration Circuit 658 is a complete power management system using the LTC3456 for portable applications powered by a wall adapter, a USB port or a 2-cell alkaline battery, in that order of priority. DC658 provides three outputs: a 1.8V, 200mA core supply, a 3.3V, 150mA main supply, and a 3.3V, 50mA Hot Swap supply. All outputs are discharged to ground during shutdown. The synchronous buck (1.8V output) and the second converter (which operates as a buck or a boost depending on the power source, and provides 3.3V @ 150mA and 3.3V @ 50mA outputs) accept a 2V to 3.2V battery input or USB/Wall adapter input.

The LTC3882 is a dual, PolyPhase DC/DC synchronous step-down switching regulator controller with PMBus compliant serial interface. It uses a constant frequency, leading-edge modulation, voltage mode architecture for excellent transient response and output regulation. Each PWM channel can produce output voltages from 0.5V to 5.25V using a wide range of 3.3V compatible power stages, including power blocks, DrMOS or discrete FET drivers. Up to four LTC3882s can operate in parallel for 2-, 3-, 4-, 6- or 8-phase operation.LTC3882 system configuration and monitoring is supported by the LTpowerPlay? software tool. The device?s serial interface can be used to read back input voltage, output voltage and current, temperature and fault status. A wide range of operating parameters can be set via the digital interface or stored in internal EEPROM for use at power up. Switching frequency and phase, output voltage and device address can also be programmed using external configuration resistors.
