Switching power supplies, including:


A buck switching circuit for reducing the input voltage and a boost switching circuit for increasing the input voltage.
a plurality of coils connected to the step-down and step-down switching circuits for storing and releasing energy; a capacitor for smoothing the output from the step-down and step-up switching circuits;


An amplifier for comparing the voltage on the capacitor with a reference voltage and amplifying the voltage on the capacitor; characterized in that:
a first triangular wave generator circuit, the output of which is within a voltage range;


- a second triangular wave generator circuit having an output with a voltage range different from the voltage range of the output of said first triangular wave generator circuit;


a first comparator that drives the buck switching circuit based on a result of comparing the output of the amplifier and the output of the first triangle wave generator circuit; and a second comparator, which compares the output of the amplifier with the second triangle wave generator electrical
The output of the circuit results in driving the boost switching circuit.
