Abstract

Disclosed is a gate control circuit that generates a gate control signal of an output transistor connected between an application end of a power supply voltage and an application end of an output voltage. The gate control circuit includes a first current source connected between the application end of the power supply voltage and the application end of the output voltage, a second current source connected between an application end of a booster voltage and an application end of a reference voltage, the booster voltage being raised to a voltage value higher than the power supply voltage in a steady state, an output stage that uses at least one of the first and second current sources to generate a gate charge current for charging a gate of the output transistor, and a controller that uses at least one of the first and second current sources according to the output voltage.
