ADM00811

The ADM00811 from Microchip is a MIC7400 5 buck 1 boost programming regulator evaluation broad. MIC7400 evaluation board was developed to evaluate the capabilities of the MIC7400 power management integrated circuit (PMIC). The device features 5 DC to DC buck converter capable of delivering 3A each and a boost converter with a 200mA current capability ?and I2C programmable output voltages. The MIC7400 evaluation board also features the MCP2221 USB to I2C bridge that enables direct communication and programming functionality by connecting the MIC7400 to the Graphic User's Interface (GUI).
