USB 0.9V – 5V TO 5V DC BOOST STEP UP

🔹 0.9V – 5V to 5V DC Boost Step-Up Converter Module – USB Output

This ultra-low input voltage boost converter module is designed to step up voltages as low as 0.9V to a stable 5V DC output. Featuring a built-in USB female port, it’s perfect for battery-powered projects, energy harvesting, and creating USB power sources from single-cell batteries or solar cells.

✅ Specifications:

• Module Type: Boost (Step-Up) DC-DC Converter

• Input Voltage: 0.9V – 5V DC

• Output Voltage: 5V DC (Fixed)

• Output Current: Up to 500mA (depending on input voltage)

• Conversion Efficiency: Up to 85% – 90%

• Switching Frequency: 150kHz – 500kHz (varies by module)

• Output Interface: USB Female Port (USB-A)

• Input Interface: Solder pads / Wires

📦 Applications:
✔️ Powering USB devices from single-cell batteries (AA, AAA, 18650)
✔️ Solar-powered USB chargers
✔️ Battery-operated projects requiring 5V output
✔️ Power banks and portable chargers
✔️ Energy harvesting systems
✔️ Arduino and microcontroller power supplies
✔️ Recharging phones from low-voltage sources

⚠️ Important Note:
Output current capability depends on input voltage. Higher input voltage = higher output current. At very low input (0.9V), output current will be limited.
