Resonant transformers – preferred sizes

  • Preferred sizes optimal for high efficiency LLC resonant converters, with integrated resonant inductance.
  • Suited for converters based on chips produced by ST Microelectronics, Fairchild, Texas Instruments, ON Semiconductor, Motorola, NXP, Power Integrations, Infineon, International Rectifier and many others.
  • Operating frequency 40KHz to 300…600KHz.
  • High creepage/clearance/DTI for reinforced insulation according to EN61558, EN60950, etc.
