Multiple Output Power Source – Dual 10V (+/-10V), 5V DC, 3.3V DC from 9V Battery


This is a multiple output power converter module that provides +/-10V (Dual 10V), 5V DC, and 3.3V DC from a 9V PP3 battery. This is a very useful project that has been designed for low-load current applications. Dual +/-10V output from a 9V battery is a key feature of the project. The battery holder can be mounted on the backside of the PCB. An onboard slide switch provides power ON/OFF. Onboard LED indicates the power. LM1117-5V chip provides 5V DC output from 9V Battery, further, an LM1117-3.3V regulator is provided to step down the 5V to 3.3V DC. MAX680 charge pump chip provides +/-10V from 5V.
