- Wed Oct 26, 2016 10:24 am #57155 After using generic DC-DC switching modules for all my projects so far, I would now like to advance to making my own integrated boards with on-board power management.

After playing around with TI's WebBench, I am trying to decide between the following choices

TPS54302

TPS62177

TPS62291

Ideally, I would like to have a solution that works efficiently for a voltage range of 4.5~12v, while being most efficient at ~5v.

What are the main characteristics I should look for in the design, leading to an efficient converter for the ESP8266?

- Wed Oct 26, 2016 7:05 pm #57188 From the voltage range you specified it looks that you are not going to be using a lithium battery. While you want high efficiency you didn't indicate why. As it is unclear about how you want to use it it is hard to make any suggestion on a prefered part other than the one with the wide voltage range. That is the only one that meets the 12 volt wish.

your input range is rather limited ..
