Analog Devices Inc. LTC2971 Demo Board (DC2875A)

Analog Devices Inc. LTC2971 Demo Board (DC2875A) is a demonstration system for the LTC2971 Power System Manager that interfaces with various regulators. This board comprises all the circuitry needed to demonstrate a power system utilizing two 2-channel LTC2971 devices that manage four power supplies. The four power supplies include various switching regulators to demonstrate various methods to sense voltage and current. The DC2875A demo board provides a sophisticated 4-channel digitally programmable power supply system. The DC2875A reflects the ability of the LTC2971 to sequence, trim, margin, supervise, monitor, and log faults for the four power supplies. This demo board contains four independent power supply rails based on DC/DC switching regulators.
