Compact DC-DC buck module for DIY and embedded power
This pack supplies ten fixed-output buck converters that step a 14 V to 26 V input down to a steady 12 V at up to 3 A peak. The tiny 17.5 mm by 12 mm footprint suits space-constrained projects such as mobile power banks, camera rigs, monitoring nodes and aviation models where weight and volume are critical. Each module uses a synchronous rectifier design rated for 96 % maximum efficiency when the input-to-output differential is at least 2 V. The operating range spans -40 °C to 85 °C for harsh environments.
Input range and continuous current limits
The modules accept 14 V to 26 V DC and deliver a fixed 12 V output; they cannot operate from lower voltages such as 12 V batteries or 5 V USB sources. Peak output current is 3 A, but sustained loads should stay below 1.8 A to avoid thermal stress over long periods. Switching runs at up to 1.5 MHz, yielding a no-load ripple of 30 mV that may rise under heavier draw. No external heatsink is included, so airflow or duty-cycle management is required for continuous high-current use.
Verify your source voltage
Confirm that your power source stays within the 14 V to 26 V window under all conditions, including voltage sag under load. Measure the actual continuous current your circuit draws; if it exceeds 1.8 A you will need additional cooling or a higher-rated converter. The fixed 12 V output cannot be adjusted, so ensure your downstream electronics tolerate exactly that level. Finally, check that the 17.5 mm by 12 mm board outline fits your enclosure or PCB layout.

Questions about this item
Should I pick the 3.3 V fixed-output version or the adjustable MP1584EN module for a 12 V rail?
This pack supplies ten fixed 3.3 V step-down modules; the adjustable MP1584EN variant is a separate product and not included here.
What does the 3 A peak current mean when the board is inside my project?
The module can deliver 3 A briefly, but continuous load should stay at or below 1.8 A to avoid overheating during long runs.
My supply is 14 V — will the 12 V output stay stable?
Yes, the buck converter accepts 14 V to 26 V in and maintains a regulated 12 V out with up to 96 % efficiency when the input-to-output gap is at least 2 V.
