DISCOVER THE WORLD’S MOST EFFICIENT & ADVANCED 65W USB-C DESIGN
PSV-RDAD-65USB
The PSV-RDAD-65USB reference design has been developed to address the complex challenges associated with thermal performance in power supplies. This ground-breaking and highly anticipated development is set to revolutionize the USB-C fast charging space by offering a unique combination of features & benefits not seen in other designs.
Pulsiv OSMIUM technology has been combined with an industry standard QR Flyback and highly optimized, ultra-compact magnetics. It represents the first in a series of designs aimed at pushing the boundaries of power conversion by drastically lowering operating temperatures, minimizing losses, and reducing size to create a sustainable platform for the USB-C standard by offering:
A peak efficiency of 96.03%
Ultra-cool thermal performance of only 30°C to 39°C above ambient
A super-compact EQ20 transformer (20% smaller than conventional RM8 alternatives)
No inrush current
No input voltage derating
Supports PD3.0, QC4.0, BC1.2, & PPS charging protocols
IDEAL APPLICATIONS: USB-C Chargers, Adapters, & In-Wall/Desk Sockets
