Compact 10-Pack Boost Modules

The KEHIPI 10-piece set provides DC-DC step-up converters that raise inputs from 0.9 V to 5 V up to a regulated 5 V output. Each board measures 11 mm by 10.5 mm by 7.5 mm with a 2.54 mm pin pitch, making them suited for breadboard prototyping and tight enclosures. Hobbyists and engineers working on battery-powered or solar projects gain ten identical modules for parallel testing or spares.

480 mA Peak Output Current

The single specification that determines fit is the maximum output current of 480 mA at 5 V. Conversion efficiency is rated at 85 percent with a 150 kHz switching frequency. Input voltage must never exceed the nominal range, and the source must supply more power than the load draws or the output will sag below 5 V.

Current Capability by Input Voltage

At 0.8 V start-up the module delivers only 7 mA, rising to 40–100 mA from 1–1.5 V, 100–150 mA from 1.5–2 V, and 150–380 mA from 2–3 V. Full 380–480 mA headroom appears only when the input exceeds 3 V. Designs needing sustained loads above 480 mA or stable 5 V from very low-voltage cells will require a higher-power converter.

Questions about this item

How much current can the module actually deliver at 5 V when the input is around 3.3 V?

With an input between 2 V and 3 V the output reaches 150-380 mA; above 3 V it can supply 380-480 mA at 5 V.

What pin spacing does the board use and will it fit a standard breadboard?

The pins are on a 2.54 mm pitch, which matches the spacing used on common breadboards and perfboards.

What are the exact board dimensions so I can check clearance in my enclosure?

Each module measures 11 mm by 10.5 mm by 7.5 mm and weighs about 1 g.
