The DC2875A is a demonstration system for the LTC2971 Power System Manager that interfaces to various regulators. The board contains all the circuitry needed to demonstrate a power system that utilizes two 2-channel LTC2971 devices that manage four power supplies. The four power supplies include various switching regulators for the purpose of demonstrating a variety of methods to sense voltage and current. The demo board provides a sophisticated 4-channel digitally programmable power supply system. The LTC2971 is a 2-channel I2C/SMBus/PMBus Power System Manager that features accurate input current and energy measurement and is capable of managing ±60V supplies. The device monitors input current and input voltage, and calculates input power and energy. The DC2875A demonstrates the ability of the LTC2971 to sequence, trim, margin, supervise, monitor, and log faults for four power supplies. The LTC2971 monitors each channel’s output voltage and output current and also monitors each channel’s external temperature sensor and its own internal die temperature. The DC2875A board contains four independent power supply rails. All four rails are based on DC/DC switching regulators. The +36V and +32V channels are managed by an LTC2971 and the ±24V channels are managed by an LTC2971-1. The board is pre-configured with these voltages and may be re-configured with feedback resistors. The LTpowerPlay® graphical user interface (GUI) supports this demonstration system and enables complete control of all the features of the LTC2971. Together, the LTpowerPlay software and DC2875A hardware system create a powerful development environment for designing and testing configuration settings of the LTC2971. LTpowerPlay stores these settings in the LTC2971 internal EEPROM or in a project file. The software displays all of the configuration settings and real time measurements from the Power System Management IC. Telemetry allows easy access and decoding of the fault log created by the LTC2971. The board comes preprogrammed with the EEPROM values appropriate for the four power supply rails on the DC2875A.

Demonstration circuit 760 is a dual, output, 1.1MHz Boost/Inverter in a 3mm x 3mm DFN featuring the LT3472EDD. The demo circuit demonstrates small size and low component count in a Boost Circuit and an Inverting Circuit. The Boost Converter is designed to convert a 2.7V–4.2V input to 15V output at 25mA– 45mA load. The Inverting Circuit generates a –8V output at 35mA–65mA from the same input. Since the maximum VIN of the LT3472EDD is 16V, this demo circuit will work well at higher inputs. The only limitation is the 10V rating of the input capacitor.
