A Switching regulated power supply regulates the output voltage by the use of a complex high frequency switching technique. They have good load and line regulation, but somewhat higher ripple and output noise than linear regulated power supplies in high frequency. They also have slower transient response, but higher efficiency. Typical applications for switching power supplies include:

general purpose use

high power

small size & light weight

long hold-up time

high efficiency

Power Factor Correction

wide input range

digital circuits
