Analog Devices LTC2970 | Demoboard DC2467

Description

The DC2467 Linduino® shield is a demonstration system for the LTC®2970 dual power supply monitor and margining controller. The LTC2970 provides a rich set of features for monitoring and controlling two power rails, including monitoring supply voltage and current, detecting faults in voltage and current, margining the supply voltage high or low, measuring temperature, and turning the supplies on and off through GPIO pins. It is fully accessible through the built-in I2C bus, which allows it to communicate with an external microcontroller or other I2C bus master. The DC2467 Linduino shield operates in conjunction with a Linduino One (DC2026) and with a DC1613 controller. The Linduino is a microcontroller that comes with a full library of existing C code examples, as well as the capability to run custom C code to control the LTC2970. The DC1613 enables a PC running LTpowerPlay® to access the LTC2970 on the DC2467. Linduino and LTpowerPlay cooperate to enable code development and debugging in one convenient system. On the DC2467 board, two DC/DC switching regulators provide +5V and –5V power outputs and demonstrate how the LTC2970 monitors and controls power supplies in a system. The LTC2970 fully controls both regulators. The LTC3604 is a buck regulator with integrated switches, configured to step down the +12V input to +5V at 1A. The LT3581 is a multifunction switching regulator, configured here as an inverting DC/DC converter producing –5V at –1A.
