Classification: CPC G  H | IPC G  H

Claim 2:
3. The internal voltage generation circuit of claim 1, wherein, in a first sub mode in the contact mode when a voltage level of the contact voltage is greater than a reference voltage,
the control signal generator is configured to disable the switched capacitor converter and the second contact switch, respectively, using the first power-down signal and the second switching enable signal, in response to the first mode signal and the second mode signal,
the first contact switch is configured to switch the contact voltage having a first voltage level to the first node as the contact mode first driving voltage, and
the bidirectional switched capacitor converter is enabled in response to the second power-down signal, and is configured to step down the contact mode first driving voltage to output the contact mode second driving voltage having a second voltage level to the second node, the second voltage level being smaller than the first voltage level.
