In summary, DC/DC converters have advantages and disadvantages compared to a low drop out regulator (LDO) or a DC/DC controller with external FETs. The features of a DC/DC converter such as adjustable soft start, phase switching and sequencing solve many problems and improve performance in certain applications. To aid in the design of a SWIFT device, SWITCHER PRO tool is available to automatically select the external components, such as the inductor, input and output capacitors, and even the compensation components, based on design requirements entered by the user.
