Abstract:
A circuit includes a reference voltage, a switched mode power supply (SMPS) loop filter circuit configured to provide an inductor current limit based on the reference voltage, and a trigger circuit configured to enable or disable the SMPS loop filter circuit. When the SMPS loop filter circuit is enabled, an output of the circuit is based on output of the SMPS loop filter circuit and output voltage of the SMPS. When the SMPS loop filter circuit is disabled, the SMPS current control circuit output is based on an estimated current limit that is increased when load current demand will increase and decreased when load current demand will decrease.

Claim (Index 1):
A switched-mode power supply (SMPS) control circuit, comprising:\n a loop control circuit comprising\n an operational amplifier having first and second inputs and an output that can be enabled and disabled, and \n a loop filter coupled between the first input and the output of the operational amplifier, wherein the first input of the operation amplifier and the loop filter are coupled to a voltage output of a SMPS; \n a first voltage reference coupled to the second input of the operational amplifier; a voltage comparator having first and second inputs and an output, wherein the first input is coupled to a current-to-voltage circuit that measures output current of the SMPS, and the second input is coupled to the output of the operational amplifier, whereby voltage applied to an inductor of the SMPS is controlled by the output of the voltage comparator; and a second voltage reference having an output coupled to the operational amplifier and the second input of the comparator, wherein when the operational amplifier output is disabled the second voltage reference supplies voltage to the second input of the voltage comparator instead of from the operational amplifier output, whereby the output of the second voltage reference is used by the voltage comparator to control the voltage to the SMPS inductor instead of from the output of the operational amplifier; and a timer having an input triggered by an event and an output used for enabling and disabling the output of the operational amplifier.
