Community Translation: ICL5102(HV)のハイサイドコアレストランスフォーマー駆動の利点
The integrated coreless transformer drive offers three benefits: efficiency, robustness and high voltage rating (up to 950V in ICL5102HV).
Customers can operate the LLC or LCC at max. 500 kHz in the steady state without raising temperature significantly in the chip. Moreover, the capability to operate at high frequency enables a smaller transformer design and further renders the possibility of an integrated design with magnetic resonant tanks. Integrating the resonant inductor into the transformer might reduce the magnetic cost by 10-15 % depending on the system power.
The switch node of the high bridge can handle negative voltage dips to as great a magnitude as positive voltage spikes, which results in a very reliable operation.
