5V 3A Dual USB Step Down Buck Converter Module

The 5V 3A Dual USB Step Down Buck Converter Module converts a DC input voltage into a stable 5V output across two USB ports. It is well suited for makers, educators, and hobbyists building robot projects, smart home devices, and custom mobile power sources.

Dual simultaneous USB outputs

Equipped with two standard USB ports, this step-down module supplies a concurrent 5V 3A output. It supports all standard 5V microcontrollers and external peripherals.

Stable voltage for continuous operation

The converter delivers a steady output with a 5.1±5%V no-load voltage rating and operates for long periods without voltage drift. This makes it dependable for sensitive controller boards and continuous automation projects.

Integrated safety and overload protection

The board features built-in reverse connection protection along with overload protection. If the current draw on any output port exceeds 3.5A, the module automatically switches off to safeguard connected equipment.

Efficient power conversion

Achieving greater than 85% conversion efficiency, the buck circuit maintains low operating temperatures with effective heat dissipation. It also features an idle static power consumption of 5mA or less.

Input range and environmental tolerance

The module accepts a 12V to 24V DC input and operates in environmental temperatures ranging from -25°C to 65°C with 0 to 95% relative humidity.

What is in the box

The package includes one 5V 3A Dual USB Step Down Buck Converter Module.
