Wide Voltage Input Range: This module can convert input voltages ranging from 1.5V to 4.2V to a stable 5V output voltage. 2. Efficient Power Conversion: The module ensures efficient power conversion by requiring the input power to be higher than the output power, preventing the output voltage from dropping below the nominal level. 3. Overvoltage Protection: With overvoltage protection, this module can safeguard against over-voltage input that could damage the device. 4. Load Protection: The module has load protection that prevents the output voltage from falling below the nominal level while supporting loads within its capacity range.
