HW-688 12V/24V to 5V 6A Buck Module

The HW-688 Buck Module is a reliable step-down power converter designed for hobbyists, engineers, and DIY enthusiasts working on automotive, solar, and USB charging projects. It supports an input power range of 9 to 36V, covering common 12V and 24V power supplies, and converts this down to a stable 5V output, making it ideal for automotive modifications, solar setups, and general DC power conversion tasks.

This module features USB mobile phone smart charging, with the RZC7512 charging control IC identifying the charging protocol and automatically switching the charging mode for safer, more efficient charging. Output capability varies depending on input range, delivering up to 5.2V at 6A (30W) when powered with 9 to 24V input, and stepping down to 5.2V at 5A (25W) or 3.5A (18W) at higher input voltages, giving it flexible high-power performance across a wide voltage range.

Common applications include USB charging for electric car or motorcycle modifications, car power modification, solar battery setups, portable USB charging, and generator USB output, making this module a versatile addition to any DIY electrical or automotive project.
