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.
