Dual Power Supply from Single Source Using LM2596 #electronics #diyelectronics #diy #ideax

Подробнее о видео

In this video, learn how to convert a single 15V DC input into a dual ±12V power supply using two LM2596 buck converter modules and a few diodes. This setup is perfect for op-amp circuits, audio amplifiers, or any electronic project that requires dual rail power from a single voltage source.

🔧 Components Used:

2x LM2596 Buck Converter Modules

2x 1N4007 Diodes

Input: 15V DC

Output: +12V, 0V, –12V

⚙️ Working Principle:
One LM2596 module is configured to step down to +12V, while the second is wired in reverse with diode orientation to generate –12V relative to the virtual ground. The diodes help stabilize and protect the virtual ground (0V reference).

💡 Note: This is a clever way to power dual-rail circuits without using a center-tap transformer or specialized ICs.
