KEHIPI 6pcs DC 4.5-20V to 5V Buck Converter 3A 10W Power Adapter
Six miniature buck converters step DC 4.5-20V down to adjustable 1-16V or fixed 5V outputs at up to 3A peak
- Weight0.032 kilograms
- Adjustable or fixed 5V output from 4.5-20V input
- Up to 97% conversion efficiency reduces heat loss
- circuit protection with enable control for safe operation
- Six compact modules each weigh only 0.032 kg
- 54 mm pin spacing suits standard protoboards
Compact buck converter pack
Six synchronous step-down modules step DC input from 4.5-20V down to a selectable fixed rail of 1.8V, 2.5V, 3.3V, 5V, 9V or 12V, or an adjustable 1-16V range. Each board handles a peak of 3A and 10W with typical efficiency above 90% at 12V to 5V 2A.
Build integration
The 2.54mm welding-pad spacing suits standard perfboard or pin-header layouts, and the enable pin lets a microcontroller shut the rail down without a series switch. No reverse-input protection is fitted, so polarity must be guarded upstream, and the tiny footprint leaves ample room inside tight enclosures.
Upgrade context
Replaces larger linear regulators or single-output modules when efficiency and flexible voltage selection matter. The jump is worthwhile for battery-powered gear needing 97% peak efficiency or for prototypes that must swap output rails by re-soldering a rear pad.

Questions about this item
What continuous current can the module supply before it overheats?
The long-term rating is within 2 A; sustained loads above that will cause the board to exceed its thermal limit.
How much heat and noise does each converter produce when running all day at 2 A?
Typical efficiency exceeds 90 % at 12 V to 5 V 2 A, so dissipation stays below 1 W; the circuit is silent with no moving parts.
What must I already have to connect the input and output?
You need a soldering iron and wire or 2.54 mm pin headers, because all connections are made by welding to the board pads.
