A driver and a driving control method for a power converter are provided. The driver includes a level shift circuit, a negative voltage generator and a first PMOS transistor. The level shift circuit provides an output signal, wherein the output signal has a first operation voltage and a second operation voltage. When the output signal received by the negative voltage generator is the first operation voltage, the negative voltage generator outputs the first operation voltage. When the output signal received by the negative voltage generator is the second operation voltage, the negative voltage generator generates and outputs a third operation voltage, and the third operation voltage is lower than the second operation voltage. A control terminal of the first PMOS transistor is coupled to an output terminal of the negative voltage generator. An output terminal of the first PMOS transistor provides a driving voltage. |
