Description
High‑Performance 5V 3A USB‑C Power Supply for Raspberry Pi 4B
This compact 5.1 V/3 A USB‑C adapter delivers the precise, stable power required by the Raspberry Pi 4 Model B. Designed with a 100 Ω built‑in shunt for accurate voltage regulation, the board includes over‑current, over‑voltage, and short‑circuit protection, ensuring safe operation even under high‑profile GPU workloads or peripheral spikes. The integrated 18 Ω PEC12 connector, a 6 m cable, and a reversible USB‑C plug provide flexibility for desk setups while keeping the overall footprint minimal.
Featuring Class‑D 95 % efficient DC‑DC conversion and 20 % noise suppression, the supply meets the Pi 4’s stringent power and thermal requirements. Its low‑profile, 22 mm × 22 mm case with a 4 mm depth sits comfortably beneath the board, while a pure silicon MOSFET minimizes losses during idle phases.
- Key Spec 1: 5.1 V output, 3 A continuous current with 5 % tolerance
- Key Spec 2: Integrated over‑current & over‑voltage protection; max surge 5 A for 3 s
- Key Spec 3: Class‑D 95 % efficiency, 1.8 kHz switching, <0.5 % ripple
- Common Use Case: Reliable, high‑current power for Raspberry Pi 4B in home media centers, digital signage, or mixed‑device IoT hubs
