Obtaining 5V from AA or AAA cells is a difficult task in terms of high efficiency and a low component count. Classic boost converter circuits are challenging to implement in portable devices like wireless mice, remotes, etc.
Presented here is a 5V Boost Converter Circuit that generates 5V from 1.5V or any single cell by using only three external components. The prototype assembled on a double-sided PCB is shown in Fig. 1.
