摘要：A voltage regulator includes an active control switch, an active sync switch, adriver circuit, and a gate resistor. The active control switch is coupled between an inputvoltage 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 andsync switches to alternately drive each of the control and sync switches into a conductingstate to produce a regulated voltage at an output of the energy storage device. Thegate resistor is coupled in series within a control path of the sync switch. The gateresistor has a resistance value that is tuned to reduce an anticipated dead time between aturn-off time of the sync switch and a turn-on time of the control switch.
