1. A voltage converter for converting an input voltage to an output voltage, the voltage converter comprising:
a coil;
multiple switches including one or more switches connected to the coil;
a modulation signal generator configured to:
receive the output voltage and one or more detection signals indicating a magnitude of a coil current flowing through the coil; and
generate a first signal and a second signal based at least in part upon the output voltage and the one or more detection signals;
an operation mode controller configured to:
receive the input voltage, the output voltage, the first signal, and the second signal; and
generate one or more mode signals based at least in part upon the input voltage, the output voltage, the first signal, and the second signal; and
a control signal generator configured to:
receive the one or more mode signals; and
generate multiple control signals based at least in part on the one or more mode signals;
wherein the one or more mode signals indicate that the voltage converter operates in an operation mode selected from multiple operation modes;
wherein the multiple control signals correspond to the operation mode selected from the multiple operation modes.
