JacobsParts Inc. 60W DC Buck Boost Converter Module Power Strip

SKU CH-J2BY-2RKHH

A 60W DC buck-boost converter module that steps input voltages from 5-30V to adjustable 0.5-30V output with current limiting and up to 88% efficiency

  • TypeDC/DC
  • Stable voltage across 5-30V input range
  • Efficient 88% peak conversion with SEPIC topology
  • Adjustable 0.5-30V output suits diverse projects
  • 60W peak power handles demanding loads
  • Compact 65x32x21mm board fits tight spaces

What it is and who it's for

This is a 60W DC buck-boost converter module that steps voltage up or down between 5-30V input and 0.5-30V output. It suits hobbyists and engineers building custom power supplies, battery chargers, LED drivers or automotive electronics where the input voltage may sit above or below the required output.

The spec that decides fit

The module delivers 60W or 4A peak, with a sustained rating of 35W or 3A, whichever limit is reached first. Low input voltage or a large step between input and output reduces the available current, so it will not suit loads that need full rated power across the entire conversion range.

Behaviour under sustained load

Efficiency reaches up to 88%, with measured results of 86.5% at 24V to 12V 1A, 85% at 12V to 16V 1.5A and 74% at 8V to 16V 1.5A. The FP5139 SEPIC topology runs at 180kHz; the unit ships with a separate heatsink that must be fitted before continuous operation at higher power levels.

Questions about this item

How much power can the 60W module actually deliver continuously?

It sustains 35W or 3A, whichever limit is reached first. Peak output reaches 60W or 4A, but sustained loads above 35W will cause the converter to cut out.

What input-to-output voltage range does the SEPIC topology support?

The SEPIC design accepts 5-30V DC in and produces 0.5-30V DC out, so it can step up, step down or pass through the voltage without changing polarity.

Will the 65x32x21mm board fit inside a standard project enclosure without extra mounting hardware?

The bare PCB measures 65x32x21mm and ships with a separate adhesive heatsink; you must stick the heatsink onto the FP5139 IC before mounting the board in your enclosure.
