Ten green circuit boards with black heat sinks and blue potentiometers

KEHIPI

KEHIPI 10PCS LM2596HV AC/DC to DC Buck Converter 3.3-33V 2.2A Power Adapter

SKU CH-E34T-HZH8M

Pack of ten LM2596HV buck-converter modules that step AC 5–30 V or DC 5–50 V down to an adjustable 3.3–33 V output at up to 2.2 A continuous current

  • Product color10PCS
  • Adjustable output from 3.3 V to 33 V suits many DC projects
  • Accepts both AC 5 V–30 V and DC 5 V–50 V input sources
  • LM2596HV high-voltage chip with heatsink handles up to 2.2 A continuous current
  • Rectifier bridge and dedicated DC port simplify dual-input wiring
  • Pack of 10 modules provides spares for prototyping or small production runs

10-Pack Adjustable Buck Converter Modules

This pack contains ten LM2596HV step-down converter boards that accept AC 5V-30V or DC 5V-50V input and deliver an adjustable DC 3.3V-33V output. Each module features a plug-in high-voltage regulator with an external heat sink for sustained 2.2A operation. The boards include silk-screen labels on both sides to assist with wiring.

Verify Input Source and Output Requirements

Confirm that your supply voltage falls within the AC 5V-30V or DC 5V-50V range before connecting. The output can be tuned between 3.3V and 33V, but the achievable voltage depends on the specific input level used. Ensure your load does not exceed the 2.2A continuous current rating for reliable long-term performance.

Integrates Into Prototypes and Repair Projects

The modules mount directly onto perfboard or terminal strips and require only an input source and a downstream load such as a microcontroller, sensor array or LED driver. The on-board rectifier bridge allows direct AC connection while the DC port offers an alternative feed. This frees the builder from designing a custom regulator circuit for common 12V, 15V or 24V rails.

Questions about this item

What comes in the 10-piece pack and is anything else needed to use the modules?

The pack contains ten LM2596HV buck converter boards with onboard rectifier bridge, DC input terminals and a heatsink; you only need to supply an AC 5-30 V or DC 5-50 V source and solder wires to the labelled pads.

Which output voltage should I set on the adjustable 3.3-33 V range for common 3.3 V, 5 V, 12 V or 24 V loads?

Turn the onboard potentiometer until the multimeter reads the exact voltage your load requires — 3.3 V, 5 V, 12 V, 15 V or 24 V are all within the 3.3-33 V adjustment span.

What does the 2.2 A continuous current rating mean when the module is mounted in a project enclosure?

With the fitted heatsink the board can deliver 2.2 A continuously; brief peaks up to 3 A are possible, but sustained higher current requires additional airflow or a larger heatsink.
