KEHIPI

KEHIPI MP1584EN 12PCS 5V Buck Converter Power Adapter 1.8A 5-30V

SKU CH-9Y4X-698VX MPN MP1584EN

Pack of twelve compact buck converters stepping 5–30 V down to 5 V at up to 1.8 A

  • Color12PCS
  • Compact 17.5×12.3×4.3 mm module fits tight spaces
  • 12-unit pack supplies multiple builds from one purchase
  • 5 V fixed output from 5–30 V input covers common sources
  • Up to 1.8 A peak current powers small loads
  • Low ripple under 30 mV at 1.5 MHz switching keeps rails clean

Compact 5 V Buck Converter Pack

This pack contains twelve miniature step-down modules based on the MP1584EN regulator. Each board accepts a DC input between 5 V and 30 V and delivers a fixed 5 V output. The tiny 17.5 mm by 12.3 mm footprint suits aircraft models and other space-constrained electronics projects.

Integration Requirements

The modules require a source voltage within the 5 V to 30 V range and correct polarity connection; positive and negative markings are printed on the reverse side. They free the builder from designing a custom 5 V rail and occupy minimal board area, leaving more room for other components in tight enclosures.

Sustained Load Behaviour

The maximum output current reaches 1.8 A, though continuous operation is recommended at or below 1.5 A where the output holds at 4.6 V. Output ripple stays under 30 mV at a typical switching frequency of 1 MHz. Extended high-current use demands adequate heat dissipation across the -40 °C to 85 °C operating temperature span.

Questions about this item

At what output current does the 5 V rail start to drop below 5 V on the MP1584EN?

The output voltage falls to 4.6 V when the load reaches 1.5 A; the absolute maximum is 1.8 A.

How much heat must be managed when running these modules continuously at high current?

The supplier notes that sustained high current requires good heat dissipation; the operating temperature range is -40 to 85 °C.

What input voltage range must the source supply for these buck converters to regulate to 5 V?

The modules accept 5 V to 30 V input; they will not operate below 5 V or above 30 V.
