Abstract:
A negative power supply control circuit which controls a negative voltage regulator circuit based on a positive voltage control signal, the negative power supply control circuit including: a control signal input terminal; a negative voltage input terminal; a negative voltage control signal output terminal; a voltage current conversion circuit; a first current source; and a first clamp circuit, wherein the first clamp circuit clamps a voltage at a first intermediate point between the first clamp circuit and the first current source by limiting a current flowing in the first clamp circuit according to the voltage at the first intermediate point in a period when a current flows in the voltage current conversion circuit, and the negative voltage control signal is generated based on a voltage or a current in a current path through the voltage current conversion circuit, the first clamp circuit and the first current source.

Claim (Index 1):
A negative power supply control circuit which controls a negative voltage regulator circuit based on a positive voltage control signal, the negative power supply control circuit comprising:\n a control signal input terminal to which the positive voltage control signal is input; a negative voltage input terminal to which a negative power supply voltage is input; a negative voltage control signal output terminal to which a negative voltage control signal is output; a voltage current conversion circuit which is connected between the control signal input terminal and the negative voltage input terminal, and causes a current to flow based on the positive voltage control signal; a first current source which is connected in series with the voltage current conversion circuit, and is able to draw a current into the negative voltage input terminal; and a first clamp circuit which is connected in series with the voltage current conversion circuit and the first current source between the voltage current conversion circuit and the first current source, wherein the first clamp circuit clamps a voltage at a first intermediate point between the first clamp circuit and the first current source by limiting a current flowing in the first clamp circuit according to the voltage at the first intermediate point in a period when a current flows in the voltage current conversion circuit, and the negative voltage control signal is generated based on a voltage or a current in a current path through the voltage current conversion circuit, the first clamp circuit and the first current source.
