AC/DC Converters ICs (PWM / Quasi-Resonant)

ROHM's large current external FET controller type switching regulators are compatible with virtually all switching power supply applications due to their wide input voltage range, multi-operation capability (step-up/negative voltage/step-down), and flexible operating frequency.

ROHM AC/DC Designer

ROHM AC/DC Designer easily supports circuit designs. It searches items according to the conditions in the Parameter. When the D button is clicked, it draws out the reference circuit, and automatically designs the specification of the Trans.

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。
