High-efficiency USB Type-C Power Delivery architectures for compact chargers that combine programmable output, fast negotiation, robust VBUS protection and high power density.
PD fast chargers convert a universal AC input into a programmable, isolated USB-C output while continuously coordinating power conversion with cable and sink-device negotiation. The architecture combines input protection and rectification, active PFC, an isolated high-voltage DC/DC primary stage, low-loss synchronous rectification, protected VBUS switching and a controller that manages USB Power Delivery, PPS regulation, startup, telemetry and fault recovery.
AC input conditioning, active PFC, isolated high-voltage conversion, synchronous rectification, protected VBUS delivery and USB PD / PPS protocol control.
Explore the PD fast-charging architecture through an interactive image map. Select PFC, the isolated primary power stage, synchronous rectification, VBUS, or Controller & Protocol to review its design role and recommended MOT device categories.
The solution combines universal-input protection, active PFC, an isolated flyback, active-clamp flyback or resonant primary stage, synchronous rectification and a protected VBUS path. The controller coordinates voltage and current regulation with USB-C attach detection, PDO selection, PPS commands, cable capability and fault handling so power-stage behavior remains aligned with every negotiated operating point.
The same functional platform can be adapted across compact wall chargers, travel adapters, notebook supplies, docking stations, display power modules and multi-port desktop chargers. Semiconductor voltage rating, switching frequency, magnetic design, VBUS current capability, protocol firmware and thermal strategy can be scaled to match the required power profile and enclosure volume.
PFC switches and controllers, high-voltage primary MOSFETs, gate drivers, low-resistance secondary MOSFETs, synchronous-rectifier controllers, VBUS load switches, current-sense and protection devices, USB PD / PPS controllers and interface components provide a practical platform for efficient, safe and interoperable fast-charging designs.
