Voltage converter having switching element with variable substrate potential |
| 摘要 |
In order to improve drive performance of a voltage regulator (on resistance of an output transistor) while suppressing increases in surface area resistance of an output transistor is reduced by changing the threshold voltage of the output transistor by controlling the back-gate voltages of output transistors of a voltage regulators.
