SKU CH-7KVV-A6F29

Steps 8–32 V input down to 3.3 V at 3 A with 95 % efficiency and full protection in a 43 × 22 × 11 mm case

  • Weight0.03 lb
  • Efficient power conversion with up to 95% efficiency
  • Wide 8V-32V input suits 12V and 24V systems
  • Multiple protections guard against faults and reverse wiring
  • Compact 43*22*11mm case fits tight installations
  • Operates from -40 to 80°C for harsh environments

Purpose and Applications

The KEHIPI buck converter steps a DC input between 8V and 32V down to a stable 3.3V at up to 3A, delivering 9.5W. It suits vehicle, RV, solar-panel and industrial projects that need a compact 3.3V rail from a 12V or 24V source.

Thermals and Efficiency

Natural cooling and a conversion efficiency up to 95% keep heat low in normal use. The ultra-thin protective case operates across a working temperature range of -40 to 80°C while over-current, over-heating, reverse-connection and short-circuit protections guard the circuit.

Build Integration

The module measures 43 by 22 by 11 mm and weighs 0.03 lb, fitting tight enclosures. Red and black input leads accept 8V to 32V; white and black output leads provide 3.3V. Waterproof, dust-proof, moisture-proof and shock-proof construction simplifies mounting in exposed locations.

Questions about this item

How do I wire the red, black, and white input and output leads on this buck converter?

Connect the red wire to the positive input terminal, the black wire to the negative input terminal, the white wire to the positive output terminal, and the second black wire to the negative output terminal.

What protection features might activate and require a reset or replacement after a fault?

Over-current protection, over-heating protection, input reverse connection protection, and short-circuit protection are built in.

At what ambient temperature does the converter reach its operating limit during sustained loads?

The working temperature range tops out at 80 °C; sustained use above this limit will trigger the over-heating protection.
