Features:

  • High-efficiency DC-DC boost conversion circuit.
  • Converts low input voltage (0.9V–5V) to stable 5V USB output.
  • Compact and lightweight design for portable applications.
  • Supports battery-powered systems and low-voltage sources.
  • USB Type-A output for direct device connection.
  • Built-in voltage regulation for stable output.
  • Low quiescent current for energy-efficient operation.
  • Ideal for DIY electronics and embedded systems.

 

Principle of Work:

The module operates using a DC-DC boost conversion principle, where electrical energy is transferred through an inductor and controlled switching circuit to increase voltage.

  • Energy Storage: The inductor stores energy when the internal switch is ON.
  • Energy Release: When the switch turns OFF, the stored energy is released at a higher voltage.
  • Voltage Regulation: A feedback circuit stabilizes the output at 5V.
  • USB Output: The regulated voltage is delivered through a USB port.

 

First Time Starting:

  • Connect a DC power source (0.9V–5V) to the input terminals.
  • Ensure correct polarity: VIN+ to positive and GND to negative.
  • Connect your device to the USB output port.
  • Verify that the output voltage is stable at 5V before connecting sensitive electronics.
  • Use a suitable battery source for optimal efficiency (single-cell Li-ion or AA battery recommended).

 

Applications:

  • DIY power banks.
  • Portable USB power supply systems.
  • Arduino and ESP8266/ESP32 projects.
  • Battery-powered IoT devices.
  • Emergency backup power systems.
