Technical Specifications
Component Description
27W Power Supply for Raspberry Pi 5 – Reliable High‑Performance Power
Designed to meet the higher current requirements of the Raspberry Pi 5, this 27 W regulator delivers a stable 5 V output at 5.4 A, ensuring consistent performance for high‑speed CPUs, GPU workloads, and extensive USB peripherals. Built with a fully integrated switching module, the supply incorporates a 120 kHz inductor and a high‑efficiency 42 V DC‑DC transformer, which reduces heat generation and extends component longevity. The chassis includes an industrial‑grade metal housing, dual USB‑C and 5 V/2.1 mm barrel connectors, and a 10 A fuse for over‑current protection.
Long‑wave EMI filters and cut‑off capacitors keep emissions below EU and FCC limits, while a low‑profile design keeps board space to a minimum. The supply is ideal for embedded developers, makers, and lab environments where consistent 5 V rail performance is crucial.
- Output: 5 V, 5.4 A (27 W) with <1% droop under load
- Efficiency: 94 % at 50 % load, <88 % across 10–100 % load range
- Protection: Short‑circuit, over‑current (10 A fuse), over‑temperature, and input voltage drop (4.75–5.25 V)
- Common Use Case: Powering a Raspberry Pi 5 for edge‑AI projects, high‑bandwidth data logging, and multi‑USB peripheral hubs
