Analog Devices LTC2972 | Demoboard DC2675A

Description

The DC2739A is a two-board demonstration system consisting of the DC2675A and DC2363A. The DC2675A contains all the circuitry needed to use two LTC®2972 Power System Managers to control four power supplies. The DC2363A contains four power supplies (LTM®4644-1quad 4A µModule® regulator) which are configured to be controlled by the two LTC2972 devices. The DC2363A and DC2675A demo boards together provide a sophisticated 4-channel digitally programmable power supply system.The LTC2972 is a 2-channel I2C/SMBus/PMBus Power System Manager that features accurate input current and energy measurement. The device monitors input current and input voltage, and calculates input power and energy. The DC2675A demonstrates the ability of the LTC2972 to sequence, trim, margin, supervise, monitor, and log faults for four power supplies. The LTC2972 monitors each channel’s output voltage and output current and also monitors its own internal die temperature.
