The Mini DC-DC Buck Converter is a high-efficiency power module designed to step down voltages from 4.5V-16V to either 3.3V or 5.2V, supporting up to 4A of current. It features a robust build with 2 ounces of copper coating and immersion gold technology for enhanced durability and performance. The converter includes adjustable voltage settings and control pins for flexible usage. Ideal for charging mobile phones and other electronic devices, it ensures reliable performance even under high loads.
Specifications of Mini DC-DC Buck Converter
- Input Voltage: 4.5V - 16V
- Output Voltage: 5.2V (default), adjustable to 3.3V
- Output Current: Up to 4A
- Conversion Efficiency: Ultra-high efficiency
- Control Pins:
- EN Pin: High level enables output, low level disables output
- FB Pin: Allows output voltage adjustment via voltage dividing resistor
- Temperature: Maximum 75°C under test conditions (12V input, 5.2V/4A output, 30°C room temperature)
- Material: 2 ounces of copper coating, immersion gold technology
- Dimensions: 16mm x 13mm (approx.)
How to Use
- Default Settings: The module comes preset to output 5.2V, ideal for compensating line loss when charging devices.
- Adjusting Voltage: To change the output to 3.3V, use a soldering iron to disconnect the soldering pad. Alternatively, adjust the output voltage by modifying the FB pin voltage dividing resistor.
- Control Output: Use the EN pin to control the output. Apply a high level to enable and a low level to disable the output.
- Heat Management: Ensure proper heat dissipation by connecting the GND pin to additional copper foil if needed, especially in high-current applications.
