Voltage Regulators with Multiple Transistors |
| 摘要 |
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. |

1. A voltage regulator having an input terminal and a ground terminal, the voltage regulator comprising:
a high-side device coupled between the input terminal and an intermediate terminal, the high-side device including 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; a low-side device coupled between the intermediate terminal and the ground terminal; and a controller that drives the high-side and low-side devices to alternately couple the intermediate terminal to the input terminal and the ground terminal. |
