Voltage regulation system and method for providing power to a load

A method for providing power to a load, the method comprising:

• setting an operating voltage of the load at a first voltage level which corresponds to a first voltage requirement of the load;
• receiving a second voltage requirement of the load which is different than the first voltage requirement;
• producing a voltage ramp signal which transitions from the first voltage level to a second voltage level which corresponds to the second voltage requirement at a defined ramp rate;
• ramping the operating voltage from the first voltage level to the second voltage level at the same ramp rate as the voltage ramp signal, but with a lag between the voltage ramp signal and the ramp in the operating voltage;
• and
• compensating the voltage ramp signal by adding a post-ramp offset to the end of the voltage ramp signal, the post-ramp offset comprising an offset amplitude and a hold-time.

A voltage regulation system for providing power to a load, the voltage regulation system comprising:

• a voltage regulator operable to:
• set an operating voltage of the load at a first voltage level which corresponds to a first voltage requirement of the load;
• receive a second voltage requirement of the load which is different than the first voltage requirement;
• produce a voltage ramp signal which transitions from the first voltage level to a second voltage level which corresponds to the second voltage requirement at a defined ramp rate;
• and
• ramp the operating voltage from the first voltage level to the second voltage level at the same ramp rate as the voltage ramp signal, but with a lag between the voltage ramp signal and the ramp in the operating voltage;
• and
• a compensation circuit configured to compensate the voltage ramp signal by accounting for a voltage drop across an output capacitor of the voltage regulator,
• wherein the compensation circuit is configured to account for the voltage drop across the output capacitor, by adding the voltage drop to the second voltage level if there is a positive voltage change and subtracting the voltage drop from the second voltage level if there is a negative voltage change.
