1. MP2229 is a chip with adjustable output and soft start time of ns. Can I use LMR14030-Q1 to replace it with PIN 2 PIN?

2. I see the soft start time of the LMR33630/LMR23630 in the manual is 5ms. I understand it?

Thank you!

The first one I wrote wrong, I want to ask is LMR33630/LMR23630, not LMR14030

HI Meng,

WIth Pin2pin compatibility and replacing MP2229 with LMR33630/LMR23630, do you mean using the same board and just swapping the ICs?

1. PIN 2 PIN is a pin and function replacement. Can these 3 chips from TI replace the MP2229?
2. What is the soft start time of these 3 ICs?

1. No Its not pin to pin equivalent . Functionally too its not equivalent as 2229 is a lower Input voltage 6A part while LMR33630 is Wider VIn 3A part .

2. Yes LMR has internal fixed SOft start time .
