Introducing the PTLA / PTLC Series: YAGEO Group Expands its 3.6kW LLC Transformer Portfolio

YAGEO Group proudly expands its power magnetics portfolio with the introduction of the PTLA / PTLC Series 3.6kW LLC Transformer, engineered for high power density, scalability, and cost efficiency in demanding power conversion applications.

Delivering up to 3.6kW in a compact 53 × 52 × 43 mm form factor, the PTLA / PTLC Series combines performance and integration flexibility for next-generation systems. Designed with 4.2kVrms isolation, basic insulation, and 5mm creepage and clearance distance, it meets stringent safety requirements while maintaining a compact footprint.

Innovative Magnetic Design Eliminates External Components At the core of the PTLA / PTLC Series is its advanced magnetic construction, concentrating 6.4µH of controlled leakage inductance on the primary side, making all leakage inductance available for the resonant circuit.

By integrating this controlled leakage inductance into the resonant circuit, the transformer:

  • Eliminates the need for an external resonant inductor
  • Reduces overall magnetic component count
  • Lowers BOM cost
  • Minimizes required PCB real estate

This results in a cleaner, more cost-optimized LLC topology design without sacrificing electrical performance.

Engineered for Reliability and Automotive Readiness The PTLA / PTLC Series features full winding automation for higher reliability and is designed according to IATF requirements, making it automotive ready. It is also compatible with AEC-Q200 qualification requirements and compliant with RoHS, REACH, and Halogen Free standards. With its modular and scalable design, the platform can support higher power requirements and evolving system architectures

Target Applications – The PTLA / PTLC Series is well suited for high-performance power applications including EV charging, AI computing, data servers, telecom Infrastructure, intermediate bus converters, and power supplies.
