8.2.2 Systems Example - TPS61230A with Feed Forward Capacitor for Best Transient Response

As for the heavy load transient applications such as a 2 A load step transient, a feed forward capacitor in parallel with R1 is recommended. The feed forward capacitor increases the loop bandwidth by adding a zero. This results in a lower output voltage drop, as shown in . See Application Note SLVA289.for the feed forward capacitor selection.
