4-Port USB Step-Down Power Supply Module – A5268 Chip DC 12V/24V to 5V 5A Buck Converter Board in Pakistan

Overview 

The A5268 4-Port USB Buck Converter is engineered to provide reliable, high-current 5V power from higher-voltage DC sources. Driven by the robust A5268 switching regulator chip, this module features synchronous rectification achieving over 94% conversion efficiency, minimizing heat dissipation. With four standard USB Type-A output ports, it is ideal for powering multiple microcontrollers (like ESP32 or Raspberry Pi Pico clusters), charging mobile devices in vehicles, or running multi-camera smart home setups.

Key Features 

• Quad USB Outlets: Features four standard USB-A ports to drive or charge multiple 5V devices concurrently.

• High-Efficiency Buck Topology: Advanced A5268 synchronous switching architecture minimizes energy loss and thermal build-up.

• Robust Protection Mechanisms: Includes built-in thermal shutdown, over-current limiting, and short-circuit protection that safely cuts output voltage during faults.

• Wide Input Range: Comfortably accepts standard 12V automotive power lines, 24V industrial rails, or multi-cell battery packs.
