Could you let me know how to calculate Css value of LTM8055 ? How big is the capacitor max ? For example, is 47uF OK ?
The customer considers the startup time would like to be 150msec after raising the RUN pin voltage above 1.2V.
Sorry for my pushing. Anybody could help my question ?
Feedback from design: Unfortunately, there is no equation. The SS cap clamps the VC node, but the voltage at which the switching starts and the regulator comes into regulation varies with the IC and is also dependent upon the load.
