Mini DC-DC 3A Step Down Power Supply Module

Buck Voltage Converter With Adjustable or Fixed Output

Ultra-compact step down DC-DC power supply module features a variable DC output or a fixed output of 1.8V, 2.5V, 3.3V, 5V, 9V or 12V. Board measures only 20mm (L) x 11mm (W) x 5mm (H).

The module is capable of delivering output currents of up to 3A with additional cooling. Current outputs of 1.5A are practical without any additional cooling or heatsink.

The output voltage is variable by using the onboard variable resistor. For fixed voltage stability, the variable resistor can be disabled and a solder-pad formed across one of the preset fixed out voltage options from the back of the board.

Specifications:

  • Input Voltage: DC 4.5V-18V (Input voltage should be a minimum of 1V higher than expected output voltage)
  • Output Voltage: Adjustable or fixed output (1.8V 2.5V 3.3V 5V 9V 12V)
  • Adjustable Range: 0.8-17V
  • Output Current: 3A (max with additional cooling).
  • Output Current (standard): 1.5A without additional cooling
  • Efficiency: 97.5%(max)
  • Switching Frequency: 500KHz
  • Board Size: 20mm (L) x 11mm (W) x 5mm (H)
