LTC3880, LTC2974, & LTC2977 Demo Board

Analog Devices Inc. LTC3880, LTC2974, and LTC2977 Demo Board is used to showcase the LTC3880, LTC2974, and LTC2977 devices. The LTC2974 and LTC2977 are I²C/ SMBus/PMBus power system managers with EEPROM. The LTC3880 is a dual output PolyPhase® step-down DC/DC controller with digital power system management. The LTC3880 monitors and controls 2 power supply rails, the LTC2974 monitors and controls 4 supplies, and the LTC2977 monitors and controls 8 supplies. The LTC3880, LTC2974, and LTC2977 Demo Board demonstrates these devices' ability to sequence, trim, margin, supervise, monitor, and log faults for fourteen power supplies. Each power supply channel's output voltage is monitored and each device monitors its own internal die temperature. Six channels have current and external temperature sensing.
