DC-DC converters are an important aspect in portable electronic devices such as cell phones, laptop computers and electric cars which power are supplied primarily from batteries. These electronic devices may require several voltage level requirements for different parts of the device. DC-DC converter is a method to convert a voltage level to another voltage level to suit the application needs rather than having multiple batteries to suit each and every part of a particular application. Generally, there are two different methods used to convert DC voltages, namely switched-mode fixed frequency pulse width modulation (PWM) DC-DC converter and the variable frequency quasi-resonant converters. Switched-mode fixed frequency pulse width modulation (PWM) DC-DC converter usually has high electronic noise and is usually complex.
