How to Select Analog and Power Devices for MCU System Design?
Selecting an appropriate MCU is just one of the steps of embedded system design; designers need to put more efforts into the selection of peripherals to build a complete solution. The following sections will introduce how to select peripherals for MCU, including power, voltage supervisor, Operational Amplifier, etc. Power Moduleļ¼ As an indispensable part of any electronic product, power device deserves its important position in design. Because the MCU features low power consumption, the selection of power devices appears simply in a wide range. Typically, the output current range from 300 mA to 3 A can meet the requirements for power supply of the system as long as the output voltage level is satisfying. Accurate selection of power supply has to be determined by the actual MCU part number and the complexity of the system. Based on the considerations that the different core voltages are required by the MCUs using different process, and some of MCUs has inbuilt LDO or DC-DC devices to pr
