Abstract

See full text

A current mode control regulator including a control circuit and a current generator. The control circuit regulates an output voltage based on a reference voltage using current mode control. The current generator applies an adjust current to a feedback current signal, in which the adjust current is proportional to a difference between a voltage indicative of the output voltage and the reference voltage to emulate an AC load resistance at an output of the current mode regulator. A load resistor emulator emulates an AC load resistor to increase the phase margin of current mode control regulator when operating without a battery coupled to the output, such as when the battery is physically removed or otherwise electrically disconnected. Operation is not substantially changed when the battery is connected, so that the desired phase margin is achieve with or without the battery.
