Ten tiny green circuit boards with silver components and solder pads

KEHIPI

KEHIPI 10PCS DC-DC Buck Step Down Module MP1584EN 9V 3A

SKU CH-XS95-REDSV

Pack of ten ultra-compact buck converter modules stepping 11–26 V input down to a fixed 9 V output at up to 3 A peak

  • Product color9 V
  • Product dimensions17.0 in × 12.0 in × 4.0 in
  • Compact 17.5×12×4.3 mm board saves space in tight builds
  • 96 % peak efficiency reduces heat and extends battery run-time
  • 5 MHz switching keeps output ripple low at 30 mV
  • 3 A peak output handles demanding loads with 1.8 A continuous rating
  • Ten-module pack supports multiple projects or spares

Compact 10-Pack Buck Converter

This pack contains ten identical step-down modules built around the MP1584EN regulator. Each board accepts 11 V to 26 V input and delivers a fixed 9 V output at up to 3 A peak or 1.8 A continuous. The tiny 17.5 mm by 12 mm footprint suits space-constrained electronics work.

DIY Builders and Vehicle Projects

Makers who need multiple regulated 9 V rails for camera rigs, monitoring gear or low-power vehicle accessories will find the quantity and size convenient. Anyone requiring adjustable output, higher continuous current or input below 11 V should choose a different module.

Fixed 9 V Output at 3 A Peak

The single specification that decides fit is the non-adjustable 9 V output with a 3 A peak rating and 1.8 A sustained limit. If the load needs a different voltage or more continuous current, this module will not meet the requirement.

Questions about this item

How do I confirm the module delivers a stable 9 V under load?

Measure the output with a multimeter while drawing up to 1.8 A; it should read 9 V with ripple around 30 mV and the IC temperature staying below 85 °C.

What does the 10-piece pack contain and is anything else required?

The pack includes ten MP1584EN buck converter boards; you will need a 11–26 V DC source, wiring, and a load that does not exceed 1.8 A continuous.

Which version should I choose if my supply is a 12 V vehicle battery?

The 9 V fixed-output module accepts 11–26 V input, so it works directly from a 12 V or 24 V vehicle system without any adjustment.
