Eight small green circuit boards with adjustable potentiometers

KEHIPI

KEHIPI 8 Pack MP1584EN Buck Converter Module 4.5-28V to 0.8-20V 3A

SKU CH-H3SW-P5WR5

Eight buck converter modules step 4.5–28 V inputs down to an adjustable 0.8–20 V output at up to 3 A with 92 % efficiency

  • Product colorGreen Adjustable
  • Adjustable 0.8 V to 20 V output for precise voltage control
  • Wide 4.5 V to 28 V input range suits varied power sources
  • Up to 3 A maximum output current drives demanding loads
  • High 92 % conversion efficiency reduces heat and waste
  • Low 30 mV ripple ensures clean power for sensitive electronics

Eight-Module Buck Converter Kit

The KEHIPI pack supplies eight MP1584EN step-down modules for hobbyists and engineers who need multiple adjustable rails in prototypes, test rigs or permanent low-power installations. Each board accepts 4.5 V to 28 V in and delivers 0.8 V to 20 V out, making it suitable for Arduino, Raspberry Pi and similar micro-controller projects.

Thermal and Electrical Behaviour

Typical output current is 1.8 A with a 3.0 A maximum, while peak conversion efficiency reaches 92 %. Output ripple stays below 30 mV and the switching frequency runs at 1 MHz typically, up to 1.5 MHz. The parts are rated for continuous operation from -45 °C to 85 °C without additional cooling.

Integration Considerations

Voltage is set by turning the onboard potentiometer while monitoring the output with a multimeter. The compact green PCB leaves ample breadboard space and the wide input range lets a single 12 V or 24 V source feed several different logic levels. No heatsink, fan or specific enclosure size is mandated by the module itself.

Questions about this item

How do I install the MP1584EN buck converter and what adjustment step causes errors?

Connect a 4.5 V to 28 V source to the input pads, then turn the onboard potentiometer with a small screwdriver while measuring the output with a multimeter until you reach the desired 0.8 V to 20 V level; skipping the live measurement often leaves the output at the factory default.

What maintenance or replacement will the module need over time?

The MP1584EN has no user-serviceable parts; if output ripple rises above 30 mV or the converter no longer regulates within the 0.8 V to 20 V range after prolonged operation at up to 3 A, replace the entire module.

What limit appears first when the converter runs continuously at high load?

Thermal protection engages once the board temperature reaches 85 °C, which can occur before the 3 A current ceiling if input voltage is near 28 V and airflow is limited.
