Hi team,
My customer is going to use TPS62231. They wants to extend the start up time to reduce the inrush current.
Do you think below method in below application note works for TPS62231 as well?
Regards,
Saito
Hi Saito-san,
I will check if it is possible to extend the soft-start by an external circuit. Keep you posted for any update.

Hi Excel-san,
Thanks. Customer wants to get the answer today. So, I greatly appreciate if you could give me an answer soon.

Hello Saito-san,
TPS62230 is a fixed output voltage where FB pin is directly connected to the output so there is no possibility to implement the capacitor and diode network.
Can your customer use a device in WCSP package? TPS62802 has a soft start time of 400us (typical) which will definitely reduce the inrush current. Please see attached datasheet for reference.

Hi Excel-san,
I really appreciate your great support. It looks TPS6280x is better for customer application. Thank you for your recommendation.
