we are suffering non smooth startup issue. We found that it is due to Vin startup too slow because RT/SD pin is tie to Vin through resistor.
so, we try to fast up Vin then Vout is more smooth startup.
However, there are no extra circuit in customer board to hold SD pin to low until Vin get ready. Could we add cap on RT/SD pin to ground to delay EN time so that Vin goes higher a little to reduce this phenomenon?
