Preface-
I am designing a drone, My choice for stepping down voltage is to use a DC/DC switching converter, after using the parametric search of Digi-key, I selected TPS54495RSAT as my SMPS.
TPS54495RSAT is a dual SMPS capable of 4A@Output1 & 2A@Output2. My SMPS design will output 5V,4A@output1 & 3v3,2A@output2.
It has 2 soft start pins, as per my understanding from datasheet they are used to protect devices ie to reduce inrush current during startup as the SMPS switches with full PWM.
Problem Statement -
What should my soft start time be?
10ms ? 50ms? 100ms? this timing is what determines my capacitor value connected.
