Introducing Payton's New 500W Hybrid Transformer with Integrated Synchronous Rectification

Designing high-frequency DC/DC converters is never just about choosing the right switches or magnetic materials. One of the most overlooked challenges are the connection points between magnetics and active components, often the hottest spots in the system, and a major source of efficiency loss.

That's exactly the problem our R&D team set out to solve.

The result: A 500W hybrid transformer delivering up to 40A on the output, with Synchronous Rectification integrated directly onto the magnetic component.

Why it matters

• Eliminates lossy AC interconnections between transformer and rectifier
• Reduces hotspots and improves thermal performance
• Boosts overall system efficiency
• Shrinks footprint for compact, high-power designs
• Simplifies PCB layout and reduces EMI challenges

Payton Planar Magnetics has been a trusted supplier of magnetics for switching frequencies from 50kHz up to 3MHz – and now we are taking it a step further by integrating active components onto the magnetic itself!

And as always, customization is at the heart of what we do.

We can support integration on the secondary side based on your specific topology, current, and thermal requirements. Primary-side integration is also possible. Whether you're working on an LLC, phase-shift full bridge, active clamp forward, or another high-frequency topology, our engineering team can co-design a solution tailored to your application.
