For Switching Power Supplies, operation efficiency typically reaches 87% to 91% that is an upper limit in most cases.
Leveraging the principles and applications of LLC (Resonant Converter) circuits, our company launched a low-profile, compact, high-efficiency (test data 97%), and low-temperature-rise LLC transformer, model (LLC)EF2012P, in December 2024.
For detailed specifications of the *(LLC)EF2012P* transformer, please refer to the PDF document 
(LLC)EF2012P.pdf.
Additionally, our R&D team is pleased to provide technical support, including calculation methods, for determining and matching critical parameters such as Lr (leakage inductance), Cr (external resonant capacitance), and Fr (resonant frequency) related to LLC circuits and their peripheral electronic components.
