PRODUCTION DATA.
Certain criteria is recommended for to achieve optimized loop stability, bandwidth and switching jitter performance. As a rule of thumb, the internal ramp voltage should be 2~4 times bigger than the output capacitor ripple(capacitive ripple only). is defined to be ease-of-use, for most applications, TI recommends ramp resistor to be 187 kΩ to achieve the optimized jitter and loop response. For detailed design procedure, see the WEBENCH® Power Designer.
