Abstract
A switching power supply controller has a nominal loop gain and transient loop gain that is only activated in response to an abrupt load change in one direction. The transient loop gain may be implemented with a series-connected diode and resistor combination arranged in a feedback configuration with an error amplifier. A large load change in one direction may swing the output of the error amplifier and forward bias the diode to create a non-linear gain change.
