Abstract:
A voltage regulator includes an active control switch, an active sync switch, a driver circuit, and a gate resistor. The active control switch is coupled between an input voltage line and an input of an energy storage device. The active sync switch is coupled to the input of the energy storage device. The driver circuit is coupled to the control and sync switches to alternately drive each of the control and sync switches into a conducting state to produce a regulated voltage at an output of the energy storage device. The gate resistor is coupled in series within a control path of the sync switch. The gate resistor has a resistance value that is tuned to reduce an anticipated dead time between a turn-off time of the sync switch and a turn-on time of the control switch.
