ABSTRACT:
The invention relates to switching power supplies receiving DC input voltage, particularly for highly efficient regulators operating at high switching frequency and high power audio amplifiers. A switching power supply generally provides a pair of switching power supplies operating alternatively to supply energy to and from an output. Also provided are simplified designs of the combination of the two switching power supply circuits and the use of the present invention in a power amplifier. A switching power supply provides a pair of switching converters each having an input and output terminals, and a reference terminal being coupled to ground, the input terminal of each switching converter being coupled to the output terminal of the remaining switching converters, and a capacitor being coupled to ground, one of the converters having the input terminal coupled to receive the input signal and the output terminal coupled to the capacitor with the output signal of the switching power supply appearing thereacross.
