Abstract
Systems and methods for a voltage converter are described. A controller can include determining a pulse width modulation (PWM) on time duration being used for operating a voltage regulator. The controller can determine a switching frequency being used for operating the voltage regulator. The controller can determine whether the PWM on time duration is greater than or less than an on time reference. The controller can, in response to determining that the PWM on time duration is less than the on time reference, increase a voltage window for a PWM signal being used to operate the voltage regulator. The controller can, in response to determining that the PWM on time duration is greater than the on time reference, perform a frequency locked loop (FLL) to regulate the switching frequency.
