(secret for the detail)
problem:
when using with recommended value(Cin=C1F=C2F=CL=1uF),
inrush current had occurred at TPS60311 input and could not output 3.0V.
question:
1. To avoid generating inrush current, what value should we choose for Cin,C1F,C2F ?
CL has three cases, 1uF, 10uF, 100uF and RL changing periodic.
Can we get any formula for calculating these capacitor values in case of another CL and RL.
Same purpose as 2. , could you provide Spice model of TPS60311 ?
