Abstract:
An over current protecting circuit, used with a switching converter having a switch, having: a current limiting circuit, configured to receive a limit indicating signal and to provide an on time signal to control an on time period of the switch based on the limit indicating signal, wherein if the limit indicating signal indicates a current flowing through the switch of the switching converter is larger than a limiting threshold, the on time period of a next switching cycle of the switch is subtracted with a first period, otherwise, the on time period of the switch of the next switching cycle is added with a second period; wherein a maximum on time period of the switch is fixed to be an on time reference.

Claim (Index 3):
The over current protecting circuit of  claim 1 , wherein the current limiting circuit comprises:\n a selecting circuit, configured to receive a first period signal, a second period signal and the limit indicating signal, and to provide the first period signal when the limit indicating signal is valid, and to provide the second period signal otherwise; a timing circuit, configured to receive a switching control signal for controlling the on and off operation of the switch, and to provide a timing signal, wherein the timing signal is reset and begins timing from an initial value at the moment the switch is turned on; a summing circuit, configured to receive the on time signal of the current switching cycle and the output signal of the selecting circuit, and to provide the on time signal for the next switching cycle; a clamping circuit, configured to clamp the maximum on time signal to an on time reference signal; a register, configured to store and update the on time signal for every switching cycle; and a digital comparator, configured to receive the timing signal and the on time signal stored in the register, and to provide the switching control signal based on a comparison result of the timing signal and the on time signal.
