Product Details

Demonstration circuit 2824A-A is a single output buck converter with 4.5V to 20V input voltage range featuring the LTC7131-1, a 25A monolithic synchronous stepdown converter with a PMBus interface. The output voltage is adjustable from 0.4V to 4V and the converter can supply up to 25A of load current.

The DC2824A-A powers up to default settings and produces power based on configuration resistors without the need for any serial bus communication, which allows easy evaluation of the DC/DC converter.

To fully explore the extensive power system management features of the part, download the GUI software LTpowerPlay® onto your PC and use ADI’s USB-to-PMBus dongle DC1613A to connect to the board.

LTpowerPlay allows users to monitor fault status and real-time telemetry of input and output voltages, input and output current, and internal IC die temperature. Programmable parameters include device address, output voltage, on/off control, and fault response to output overvoltage and output overcurrent.

The LTC7131-1 data sheet gives a complete description of this part, its operation and application information and must be read in conjunction with this quick start guide for DC2824A-A.
