High-Current 5V Buck Converter

This step-down converter provides a regulated 5V DC output with up to 20A continuous current capability. It operates from an input range of 20V to 60V DC, making it suitable for use with 36V and 48V battery banks, solar charge controllers, and industrial DC distribution systems. Physical size is 60mm × 40mm × 22mm; mass is 120g. The module integrates over-temperature protection, current limiting, and input reverse polarity safeguarding. Its PCB layout prioritises thermal dissipation and EMI suppression, supporting reliable long-term deployment in embedded systems, robotics platforms, and distributed sensor networks requiring clean, high-current 5V supply rails.
