PRODUCTION DATA.
Choose a type I ripple circuit, as described in Ripple Configuration, for this example. For a constant on-time (COT) converter to be stable, the injected in-phase ripple must be larger than the capacitive ripple on COUT.
Using the type I ripple circuit equations with minimum FB pin ripple of 25 mV, calculate the value of series resistor RC using Equation 13.
Based on the calculated value of 1.1 Ω, select a standard value of 1 Ω.
