Abstract
A voltage regulator containing a bootstrap capacitor, a switching converter and a pre-charging block. The bootstrap capacitor provides a required bias voltage for a high-side switch of the switching converter. The pre-charging block charges the bootstrap capacitor upon receipt of a wake-up signal. The high-side switch and a low-side switch of the switching converter together operate to generate an output voltage based on a control signal transitioning between a first logic state and a second logic state. The high-side switch is required to be biased at a 'second voltage' exceeding a threshold voltage for fully turning ON and generating the output voltage, with such ‘second voltage’ being provided by the bootstrap capacitor upon being charged. The wake-up signal is received before start of transitioning of the control signal.
