Design Example of Non Isolated Synchronous Buck Converter based on Mixed Signal MCU MD6602

ANE0002, Reference Design describes the design example of non-isolated buck converter of full digital control using the MD6602 evaluation board (Tile). In this document, full digital control means that all processing control by digital from feed back detection of output voltage to PWM signal output for power transistor driving. The control method of power supply is voltage mode which is basic method of constant voltage output control. The phase compensation of controller calculates by DSP and consists of 2Pole-2Zero phase compensation of type II digital filter
