1 kW Ultra‑Low Profile Planar Matrix Transformer for High‑Frequency Power

1 MHz LLC Design for 800 V to 12 V Conversion

Payton Planar Magnetics continues to expand the limits of compact, high‑density power design with a new 1 kW ultra‑low profile planar transformer. Engineered for 1 MHz LLC resonant operation, this solution supports efficient conversion from 800 VDC to 12 VDC while maintaining a remarkably low profile of just 7 mm.

The transformer’s matrix architecture is designed to improve current sharing and thermal performance. Its larger effective surface area helps dissipate heat more efficiently, making the design well suited to systems where space is limited and performance requirements are high.

Reliability, Isolation, and Thermal Performance

Built for demanding environments, the transformer is specified with 2500 VDC isolation and 8 mm creepage and clearance to support high‑reliability operation. These insulation characteristics are important in high‑voltage platforms where safety, durability, and predictable long‑term behavior are essential.

The design is aimed at applications that demand both compact size and robust performance, including AI servers, data centers, aerospace systems, and next‑generation power supplies. In these settings, high efficiency and strong thermal control are key to maintaining stable operation at elevated power density.

Key Highlights

• 1 kW power capability in a 7 mm profile.
• Optimized for 1 MHz high‑frequency LLC operation.
• Matrix architecture for improved efficiency and thermal management.
• 2500 VDC isolation with 8 mm creepage and clearance.

Payton’s planar magnetics are designed to support compact, high‑efficiency power architectures across advanced computing, aerospace, and other performance‑critical industries.
