The +5V and +12V circuit formed by 2 cells

Generally, the portable electronic products powered by battery is working in a low voltage, which can reduce the number of the cells and the size of the product. Conventionally, the working voltage is 3~5V, to assure of the stability and precision, the power supply is expected to be stable. If 5V working voltage is adopted by the circuit, another higher working voltage is needed, which baffles the designer. The text is introducing a circuit composed of 2 step-up modules to solve this problem.
