Pololu 5V Step-Up Voltage Regulator U3V50F5 with Lifepo4 3.2


I am looking to use a Calb 100ah Lifepo4 cell to run a raspberry Pi project remotely. The cells have a nominal voltage of 3.2v. The pi will be using c.500ma but will occasionally pull up to around one amp. The voltage curve of the Calb cells can be found here - Calb but they drop from around 3.4 to 3v through their use.

Will the U3V50F5 U3V50F5 Step up convertor be suitable. Will it output sufficient current at these voltages?

Many thanks,


The U3V50F5 would probably be fine for your application. Just in case you are not aware of it though, you might consider our U3V70F5 instead. We recommend our newer U3V70x family of boost regulators over the older U3V50x regulators for applications that require 20 V or less since the newer regulators are smaller and can deliver more current.
