20A 300W Synchronous Buck Module

This synchronous buck module steps down DC input from 6V to 40V to a regulated 1.2V to 36V output. It delivers up to 20A continuous current with a suggested operating limit of 15A. The compact board measures 60 x 53 x 27mm and suits industrial power supply applications.

Terminal wiring and efficiency

Terminal connections simplify integration into custom panels or enclosures. The converter achieves 95% efficiency when converting 24V to 12V at 20A load. Output ripple is specified at 50mV, supporting stable voltage for sensitive downstream electronics.

For engineers needing adjustable high-current

This module fits projects requiring a wide input range and configurable output up to 36V. Builders who need isolated topologies, higher input voltage ratings, or integrated circuit-breaker protection should evaluate alternative power supply designs.

Questions about this item

Does the 20A synchronous buck module need periodic replacement of any internal components?

The module is a solid-state DC-DC converter with no moving parts or user-serviceable components, so no scheduled maintenance or part replacement is required.

At sustained load which limit appears first — the 20A maximum or the 15A suggested continuous rating?

The 15A suggested continuous rating is the practical limit for all-day operation; the 20A figure is a short-term maximum.

How much heat and noise does the 60 x 53 x 27mm unit produce when running at 15A all day?

At 95% efficiency the unit runs silently with no fan; warmth will be noticeable on the aluminium case but stays within the module's thermal design.
