Abstract :
In recent years, low output power CMOS DC-DC converters that integrate power stage MOSFETs and a PWM control circuit using CMOS process have been used in many mobile devices. In this paper, we propose the calculation method of CMOS DC-DC converter efficiency and report optimum design of CMOS DC-DC converter based on this method. By this method, converter efficiency can be directly calculated from converter specifications, dimensions of power stage MOSFETs and device parameters. Therefore, this method can be used for optimum design of CMOS DC-DC converter, such as dimensions of power stage MOSFET and switching frequency.
