DC1962C-KIT

DC1962C-KIT is a starter kit for power system management [includes DC1962C, DC1613A]. The DC1962C is a demonstration system that showcases three different Linear Technology devices: the LTC®3880, LTC2974 and LTC2977. The LTC2974 and LTC2977 devices 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 power supply rails, and the LTC2977 monitors and controls 8 power supply rails. The DC1962C demonstrates the ability of these devices 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. The DC1962C is a single circuit board that contains fourteen independent power supply rails.
