Claim 4:
5. The current detecting circuit according to claim 1, further comprising:
a fourth switching circuit electrically coupled in series with the second switching circuit, the fourth switching circuit including a fourth control terminal electrically coupled to the third control terminal of the third switching circuit,
wherein the current amplifier is configured to detect a difference between a first output voltage of the third switching circuit and a second output voltage of the fourth switching circuit, and to output a relative current to be used for detecting an output current that flows out from the output terminal,
wherein a ratio of resistance associated with the first switching circuit to resistance associated with the second switching circuit is n:1, where n is an integer greater than one, and
wherein a ratio of resistance associated with the third switching circuit to resistance associated with the fourth switching circuit is m:1, where m is an integer greater than one.
