HTX7045C LLC Half-Bridge Transformers

For isolated gate driver bias supply

HTX7045C Series transformers feature a chip-style construction – a significant advancement over traditional core and bobbin designs that not only reduces the size of the component, but also streamlines the manufacturing process, resulting in a more cost-effective solution.

It offers low interwinding capacitance (as low as 0.7 pF), making it particularly well-suited for use in isolated gate driver bias supplies employing the open-loop LLC topology to achieve ultra-low EMI noise and high CMTI (Common Mode Transient Immunity). These characteristics make it especially beneficial for high-frequency switches including SiC, GaN and IGBT technologies.

The HTX7045C is AEC qualified, making it ideal for automotive traction inverters and motor controls, automotive on-board chargers (OBC), EV charging stations, battery management systems (BMS), automotive DC-DC converters and wide range of other automotive and industrial applications.

Low interwinding capacitance to minimize EMI and achieve high CMTI (Common Mode Transient Immunity)
Optimized for isolated bias supplies for SiC and GaN gate drivers, such as Texas Instrument UCC25800-Q1
Ideal for automotive OBC and traction Inverters in EV/HEV
Designed and fabricated for systems mounted in harsh automotive conditions
2800 Vrms, 4000 VDC, one minute isolation (hipot) between primary and secondary windings.
AEC-Q200 qualified
