Abstract:
A voltage regulator has an input terminal and a ground terminal. The voltage regulator includes a high- side device, a low side device, and a controller. The high- side device is coupled between the input terminal and an intermediate terminal. The high- side device includes first and second transistors each coupled between the input terminal and the intermediate terminal, such that the first transistor controls a drain-source switching voltage of the second transistor. The low- side device is coupled between the intermediate terminal and the ground terminal. The controller drives the high-side and low-side devices to alternately couple the intermediate terminal to the input terminal and the ground terminal.
