Ten small green circuit boards with components and pins

GCON

GCON 10PCS Mini560 Step Down DC-DC Converter 3.3V 5A gender changer

SKU CH-K5PC-FWK8H

Pack of ten Mini560 buck modules converting 5-20 V input to a stable 3.3 V at up to 5 A

  • Pack of ten converters keeps spares ready
  • 3 V fixed output suits low-voltage logic
  • Up to 5 A delivers ample current headroom
  • 5–20 V input range works with common sources
  • Mini560 buck topology gives high efficiency stability

Compact 3.3V Regulator Pack

This pack contains ten MINI560 step-down modules that convert a 5V to 20V input into a fixed 3.3V rail rated for up to 5A. They suit hobbyists, repair technicians and small-batch integrators who need multiple identical buck converters for prototyping or permanent installation.

Thermals And Power Draw

Each module delivers high efficiency across the input range so heat stays low during typical loads and no active cooling is required. Quiescent draw is minimal, leaving most of the source power available to the 3.3V output without audible noise from the converter itself.

What The Bundle Changes

Ten units in one order let you populate several boards at once or keep spares on hand for field swaps without waiting for a re-order. The consistent 3.3V output across every module simplifies wiring looms and firmware calibration when the same rail feeds multiple sub-circuits.

Questions about this item

How do I wire the Mini560 step-down module into my 5 V to 20 V supply without exceeding the input limit?

Connect the source to the module’s input pins, verify the supply stays between 5 V and 20 V, then attach the load to the 3.3 V output; reversing polarity or feeding more than 20 V will damage the regulator.

What component on the Mini560 board is most likely to need replacement after prolonged 5 A operation?

The on-board synchronous rectifier and output inductor run hottest at full 5 A load; if thermal stress degrades them, the whole module is replaced rather than individual parts.

At what point does the 3.3 V output begin to droop during continuous 5 A draw?

The converter is rated for up to 5 A; sustained loads at that level will hit the current limit first, causing voltage to fold back until the load is reduced or cooling improves.
