Description

In this project we will build a low cost 5V booster circuit that provides a constant regulated output voltage of 5V from a CR2032 coin cell; we will also design a compact PCB for this boost converter so that it can be used in all our future portable projects. The maximum output current of the boost converter will be 200mA which is good enough to power basic microcontrollers and sensors.

Hi, I was wondering where you purchased the booster IC. I can't find anywhere to buy one.
