SMUGDESK LM2596S DC-DC Step Down Buck Converter Module 10PCS

SKU CH-NQMV-4W92E

Pack of ten LM2596S buck converter modules stepping DC 3 V to 40 V down to adjustable 1.5 V–35 V at up to 3 A

  • Original LM2596S chip delivers stable 3 A output
  • Wide 3 V to 40 V input suits many power sources
  • Adjustable 1.5 V to 35 V output via precision potentiometer
  • High-efficiency design with over-current, short-circuit and over-temperature protection
  • Bulk pack of 10 modules for labs, DIY and small-batch projects

Ten-piece LM2596S buck converter kit

This pack contains ten identical step-down modules built around the LM2596S switching regulator. Each unit accepts a DC input from 3V to 40V and lets you set a stable output between 1.5V and 35V with a maximum load of 3A. The bulk quantity suits laboratories, maintenance benches and small-batch development where repeatable supply rails are needed.

Compact PCB with mounting holes and screw terminals

The board layout includes fixed mounting holes and standard reserved terminals for secure mechanical attachment and reliable wiring. High conversion efficiency keeps heat low during continuous operation while built-in over-current, short-circuit and over-temperature protection guards the circuitry. These features make daily assembly and long-term installation straightforward in vehicles, surveillance gear and experimental rigs.

Replaces improvised linear regulators

The module upgrades bench setups that rely on wasteful linear regulators or one-off breadboard circuits by delivering efficient, adjustable power with proven protection. The jump is worth it when a project demands consistent voltage across multiple units or when a compact, mountable solution must survive vibration in mobile or industrial environments.
