New SiP in a compact design for highly efficient power delivery

Infineon Technologies AG launches its new CoolSET SiP, a compact, fully integrated system power controller for highly efficient power delivery of up to 60W at universal input voltage range of 85-305VAC. Housed in a small SMD package, the high-voltage MOSFET with low R DS(ON) eradicates the necessity for an external heat sink, decreasing system size and complexity. The SiP supports ZVS flyback operation, which facilitates low switching losses and low EMI signature while improving system reliability and robustness. This makes it an excellent solution for applications such as major home appliances and AI servers. Also, the controller makes it easier for developers to satisfy stringent energy standards, supporting future-proof power solutions for modern designs.

The CoolSET SiP integrates a 950V startup-cell, an 800V avalanche rugged CoolMOS P7 SJ MOSFET, a ZVS primary flyback controller, a secondary-side SR controller, and reinforced isolated communication enabled by the company's proprietary CT Link technology. This high level of integration supports the development of more sophisticated end products by greatly reducing the number of discrete components, lowering the BOM, and minimising PCB space requirements. A comprehensive set of advanced protection features simplifies system integration and permits designers more flexibility to optimise their solutions and improve the overall user experience.
