Abstract
A current detection circuit includes a processing circuit used to operate during each switch cycle which includes a first period and a second period. A cycle detecting current is provided based on the terminal voltage established on a first end of a capacitor. The terminal voltage established on the first end of the capacitor is increased during the first period using a constant current. The terminal voltage established on the first end of the capacitor varies with a low-side detecting current during the second period.
