Principle of Work:
The module uses a high-efficiency switching regulator that automatically operates in buck or boost mode depending on the relationship between the input and output voltages. An onboard microcontroller continuously monitors the output voltage and current, adjusting the switching circuit to maintain the programmed constant voltage or constant current. This ensures stable output even when the input voltage fluctuates or the connected load changes.
