Five tiny green circuit boards with solder pads and a potentiometer

KEHIPI

KEHIPI 2001708006 5pcs DC 4.5-24V to 5V 3A Buck Converter Power Adapter

SKU CH-4Z2T-RN2QN

Pack of five compact buck converters stepping DC 4.5-24V down to selectable fixed outputs or adjustable 0.8-17V at up to 3A

  • Product colorGreen
  • Product weight0.634 oz
  • Wide 4.5-24V input covers many power sources
  • 5% peak efficiency reduces heat and waste
  • 3A maximum output current drives demanding loads
  • Adjustable 0.8-17V plus six fixed voltages for flexibility
  • Enable pin allows low-level on/off control

Five-module pack for distributed 5 V rails

Each board steps a 4.5–24 V source down to a fixed 5 V at up to 3 A, giving engineers five identical regulators for parallel or separate sub-circuits in a single purchase.

Solder-only connections

All input, output and enable pins use 2.54 mm through-hole pads, so the modules cannot be plugged into breadboards or screw terminals without extra wiring. The 3 A rating requires added cooling; at 12 V in and 1.5 A out no extra heatsinking is needed.

Fixed 5 V with 3 A headroom and industrial

The preset 5 V output handles typical microcontroller, sensor and peripheral loads up to the rated current, while the –40 °C to +85 °C operating window suits automotive or outdoor deployments. No over-voltage or reverse-polarity protection is built in, so external safeguards are necessary for fault-prone environments.

Questions about this item

Should I use the fixed 5 V setting or the adjustable range for my project?

Choose the fixed 5 V pads on the back for a simple 5 V rail, or use the potentiometer to dial any voltage between 0.8 V and 17 V if you need a custom level.

What does the 3 A rating mean when the board is inside my enclosure?

The module can deliver up to 3 A, but at full load the temperature rises about 40 °C, so add airflow or a heatsink; at 1.5 A from a 12 V source it runs cool without extra cooling.

How does the 500 kHz switching frequency affect my 5 V rail?

At 500 kHz the converter keeps ripple down to 20 mV when stepping 12 V to 5 V at 3 A, giving a clean supply for sensitive logic.
