Hello.
I have an issue with battery power supply design in my project.
Requirements : input: 2.5-4.2V, output : 3.3V@0.9A.
When i used webench design, i not check a warning for bypass mode when Vin larger than Vout.
Now i need choose a replacement ic with same package with TPS61023.
Thanks for all your suggestion.

Hi Alone173

if you need regulated output voltage, I would suggest a buck-boost converter such as TPS63802. But no buck-boost has same package as TPS61023
