800V CoolMOS enheder til low-power switched-mode forsyninger
Infineon lancerer 800V CoolMOS P7-serien, der bl.a. udmærker sig ved høj effektivitet og termisk performance (in english).
Infineon Technologies introduces the 800 V CoolMOS P7 series. Based on the superjunction technology, this 800 V MOSFET combines best-in-class performance with exceptional ease-of-use. This new product family is a perfect fit for low power SMPS applications, fully addressing market needs in performance, ease of design, and price/performance ratio. It mainly focuses on flyback topologies which are typically found in applications like adapter, LED lighting, audio, industrial and auxiliary power.The 800 V CoolMOS P7 series offers up to 0.6 percent efficiency gain. This translates into 2 to 8 °C lower MOSFET temperature compared to the CoolMOS C3 or to competitor parts tested in typical flyback applications. This new benchmark results from a combination of optimized device parameters: including the reduction of more than 50 percent in E oss and Q g, as well as a reduced C iss and C oss.
The further improved performance enables higher power density designs through lower switching losses and better DPAK R DS(on) products. Overall, this helps customers to save BOM costs and reduce assembly efforts.
Ease-of-use of is an intrinsic feature designed into this product family. The integrated Zener Diode significantly improves ESD ruggedness, thus reducing ESD related production yield losses. The MOSFET is easy to drive and to design-in due to its industry leading V (GS)th of 3 V and the smallest V GS(th) variation of only ±0.5 V. This combination allows for lower driving voltage and lower switching losses. Additionally, it helps to avoid unintentional operation in the linear region.
