Abstract
A method and system to inhibit the switching of a current mode switching converter having high and low side switching elements coupled to an output inductor, the other end of which is coupled to an output node, and operated with respective modulated switching signals to regulate an output voltage Vout produced at the node. A current Ithat varies with the difference between a reference voltage and a voltage proportional to Vout is compared with and a current Iwhich varies with the current conducted by the high side switching element; the result of the comparison of Iand Iis used to control the regulation of Vout during normal operation. Current Iis also compared with a current Iwhich varies with the current conducted by the low side switching element. When I>I, a 'skip mode' is triggered during which the switching signals are inhibited.
