This document describes how to connect the I?C/S2Cwire controller board to AnalogicTech's AAT1142 dynamically programmable DC/DC buck converter. The schematic and PCB drawing of the controller board, as well as the function of each button, is described. The I?C/S2Cwire controller board contains an MCU that provides the I?C and S2Cwire interface via a five-wire ribbon cable. This controller board works as a master device in either the I?C or S2Cwire system, while the AAT1142 slave device receives data and varies the AAT1142 output voltage in response to push-button commands. The MCU is programmed with one I?C slave address.
