DC-DC Buck-Mode Power Module (8~28V to 5V 1.6A)

The DC-DC Buck-Mode Power Module is a compact step-down voltage converter that steps down 8V to 28V DC input to a steady 5V output. It provides a reliable power solution for makers, students, and hobbyists building robotics, battery-powered systems, or embedded controller projects.

Wide input step-down conversion

Accepting an input voltage range from 8V to 28V DC, this module delivers a stable 5V output with a voltage accuracy of ±0.1V. It is well suited for stepping down high-voltage battery packs or variable DC power sources without voltage shift over long periods.

Stable 1.6A continuous output

The module supplies a rated continuous output current of 1.6A, with a maximum peak output current capability of up to 3A. It features a low no-load quiescent current of 0.5mA and operates at a switching frequency of up to 0.5MHz.

Versatile project applications

This converter is suitable for powering main controller boards, communication hardware, and digital radios. It can also be integrated into DIY toy cars, custom mobile power banks, and floodlight circuits.

Dual installation options

Measuring just 16.5 x 22 mm, the board is designed for compact embedded builds. It supports installation either through surface chip-mounting or via standard 2.54mm pin header plug-in connections.

Durable operating range

Built for non-isolated operation, the module has a rated service life of 50,000 hours and an operating temperature range of -20°C to +85°C. For optimal longevity, sustained continuous loads should remain below the 3A peak limit.
