  • DC-DC Buck Converter Step Down Module LM2596 Power Supply is a step-down(buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version.

    The LM2596Â series operates at a switching frequency of 150kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators.

    This is an LM2596 DC-DCÂ buck converter step-down power module with the high-precision potentiometer, capable of driving a load up to 3A with high efficiency, which can work with Freeduino UNO, other mainboards, and basic modules. When the output current keeps greater than 2.5A (or output power greater than 10W), please add a heat sink to it.

    This device is internally compensated to minimize the number of external components to simplify the power supply design.

    Since LM2596 converter is a switch-mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators, especially with higher input voltages. The LM2596 operates at a switching frequency of 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.

  • Model: DSN6009 boost module
  • Module Properties: Non-isolated boost (BOOST)
  • Rectification: Non-Synchronous Rectification
  • Input Range: 3V ~ 32V
  • Output Range: 5V ~ 35V
  • Input Current: 4A (max), no-load 18mA (5V input, 8V output, no-load is less than 18mA. Higher the voltage, the greater the load current.)
  • Conversion efficiency: <94% (greater the pressure, the lower the efficiency)
  • Switching frequency: 400KHz
  • Output Ripple: 50mV (the higher the voltage, the greater the current, the greater the ripple)
  • Load Regulation: +/-0.5%
  • Voltage Regulation: +/-0.5%
  • Operating Temperature: -40 degree to +85 degree
  • Body Size: 43 x 20 x 12mm/1.7″ x 0.8″ x 0.47″(L*W*T)
