HTX8045C LLC Half-Bridge Transformers

For isolated gate driver bias supply

HTX8045C Series transformers build on the proven chip-style construction of the HTX family - a major improvement over conventional core and bobbin designs. This compact, surface-mount configuration reduces component size and enhances manufacturing efficiency, allowing for more cost-effective production.

With higher isolation voltage compared to the HTX7045C and low interwinding capacitance (as low as 0.55 pF), the HTX8045C is 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 HTX8045C 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 as well as a 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 the UCC25800-Q1 from Texas Instruments and the MPQ18913 from Monolithic Power Systems
Ideal for automotive OBC and traction Inverters in EV/HEV
Designed and fabricated for systems mounted in harsh automotive conditions
AEC-Q200 qualified
