Switching regulator frequency control

A system may include a voltage controller to provide a control signal, a voltage converter to receive the control signal and to change a value of an output voltage in response to the control signal, and an evaluation circuit to determine that a threshold associated with a pulse width of the control...

Beschreibung
Zusammenfassung:	A system may include a voltage controller to provide a control signal, a voltage converter to receive the control signal and to change a value of an output voltage in response to the control signal, and an evaluation circuit to determine that a threshold associated with a pulse width of the control signal has been satisfied and to change an electrical value on which a frequency of the control signal is based if the threshold has been satisfied. The voltage controller may increase the frequency of the control signal in response to the changed electrical value. The increase in frequency may be continuous and may begin at start-up.
