An electronic device needs to use a power. We have a lot of power supply circuit. We recommend the example tag: (It may make you find the circuit easier.)Fixed voltage regulator :: 3-volts :: 5-volts :: 6-volts :: 9-volts :: 12-volts :: 15-volts :: Protection :: Transformerless :: Negative Power Supplies :: Dual output power supply :: Variable DC Power Supply :: 0-30V DC Power SupplyAdjustable DC power supplies :: Switching power supply :: High current :: High voltage :: Zener Diode Regulators :: Multi voltage regulated :: 7805 Regulator Circuits :: LM317 Circuits :: PC power supply circuits
and We love renewable energy, clean, and long with solar.

2.4V to 9V Step-Up Voltage Regulator using RC4193
This is the 9V Step-Up Voltage Regulator. We used the RC4193 Micropower Switching Regulator is the base, so low current power output. But The advantage of this system is although input the voltage input change from 2.4V to 10V but a constant voltage output 9 Volt.
