      特點1 : 採用自製超接合面MOSFET 大幅節能！

      業界最高等級的高效率！

      採用自製超接合面MOSFET 大幅節能

      使用在25W轉換器時，單單換掉IC就能達到87%以上的高效率。再透過周邊零件的優化，可以達到超過90%的效率改善。
      符合新國際節能標準Energy Star 6的要求。

      大幅降低待機功耗！

      採用自製超接合面MOSFET 大幅節能

      待機時的功耗：在25W轉換器時，AC100V為20mW以下，AC230V為30mW以下，大幅低於國際標準Energy Star 6.0的100mW以下的待機功耗要求。如再針對周邊零件優化，還能進一步降低功耗。

      特點2 :產品陣容亦備有小型表面安裝型封裝！

      產品陣容亦備有小型表面安裝型封裝

      AC/DC一般多採用平面型MOSFET，散熱及小型化不易。ROHM採用超接合面MOSFET及IC設計的優化，成功達到封裝的小型化，除了標準的DIP7封裝外，產品陣容亦加入小型表面安裝SOP-8封裝。使用SOP-8封裝能減少47%的安裝面積。
