A multiphase buck type voltage regulator having at least two phases and including
a first switching means that selectively connect a supply voltage to a load through
a first current path; a second switching means that selectively connect said supply
voltage to said load through a second current path; a first activation circuit
that activates said first switching means; a first delay circuit that deactivates
said first switching means after a first period of time; a second activation circuit
that activates said second switching means; a second delay circuit that after a
second period of time deactivates said second switching means; said first period
of time depends on said supply voltage and on the output voltage; said second period
of time depends on said supply voltage and on a voltage proportional to the difference
of current that flows in said first and second current path.
