PRODUCTION DATA
Depending on the required ripple resistance when operating in COT mode, the resultant output voltage ripple may be deemed too high for a given application. One option is to place a feedforward capacitor CFF in parallel with the upper feedback resistor RFB1. Capacitor CFF increases the high-frequency gain from VOUT to VFB close to unity such that the output voltage ripple couples directly to the FB node.
