The article presents information about the low-power switch mode power supplies (SMPS). Earlier, linear-regulated power supplies were used for low-power applications due to their simplicity and low-cost. However, stringent energy-efficiency standards forced the manufacturers to replace them with SMPS. Now, SMPS are designed by using integrated circuits (ICs) which have significantly fewer components.
