AN2017.0, Application Note for Non Linear Response

AN2017.0, Application Note for Non Linear Response. The Zilker Labs Digital-DC devices incorporate a non-linear response (NLR) loop that decreases the response time and the output voltage deviation in the event of a sudden output load current step. The NLR loop incorporates a secondary error signal processing path that bypasses the primary error loop when the output begins to transition outside of the standard regulation limits. This scheme results in a higher equivalent loop bandwidth that what is possible using a traditional linear loop
