Product Overview
The USB‑C PD 20W Fast Charger PCBA is a high‑density power conversion board designed for small‑form‑factor USB‑C wall chargers. It integrates a primary controller (flyback or active‑clamp flyback), secondary‑side USB‑C PD protocol controller, synchronous rectification MOSFET, and output filtering into a PCB as small as 35×35mm. This board delivers up to 20W of power (9V/2.22A, 12V/1.67A), enabling fast charging of iPhones (50% in 30 minutes), Samsung Galaxy devices, and other USB‑C compatible phones and accessories.
With >90% efficiency and standby power below 0.075W, this PCBA meets global energy regulations (DoE Level VI, CoC Tier 2, EU Ecodesign). It replaces older 5W/10W chargers with a compact, fast‑charging solution that automatically negotiates the optimal voltage and current with connected devices – protecting both charger and phone from over‑voltage or over‑current conditions. Ideal for OEMs producing replacement chargers, travel adapters, or bundling chargers with electronic products.
