Classification: CPC G  H | IPC G  H

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