Abstract
Abstract The power section of the switching regulator is divided into two identical parts. The two parts may be connected in series when a high value of power line voltage is used. The two parts are connected in parallel when a lower value of power line voltage is used. The same value of regulated output voltage may be obtained with either the series or the parallel connection.
