thank you very much
 

hello...
i need circuit for converter dc -dc for step up and step down
my regards
 

Microchip has PIC variants that work between 2V and 5.5V. For example the PIC16LF87xA series. The only limit is the clock frequency is max 4MHz, or 3-5.5V @10MHz
 

There are a lot of PIC parts that will run at 3V. If you do not already have a part specified, go to the Microchip Advanced Part Selector (MAPS) page and select a part that meets your needs. If you do have a part that you need to use but it only runs at 5V, there may be a pin compatible part that runs at 3V.
 

For some pics even the 5 V part will work in 3 volts, but with lower speed
