伺服器（Server Board）

隨著雲端服務的普及和遠端辦公機會的增加，伺服器需要具有更快的處理速度和更大的儲存容量，以處理更多的資料。同時，由於高速化和大容量化會導致耗電量增加，為了實現高效系統，伺服器將從傳統的12V分散式系統轉向48V集中式系統。羅姆擁有支援12V分散式系統和48V集中式系統的DC-DC轉換器IC產品陣容。採用高速開關後實現了線圈尺寸的小型化，高速回應特性確保了大電流負載時的穩定供電，有助於降低伺服器主機板的功耗，提高可靠性。

Topology Selection

When designing an electronic circuit, especially power system circuits, it is necessary to select a circuit configuration (topology) that meets the required specifications because input voltage, output voltage, power, isolation, etc. vary depending on the application. The selection of the most suitable components also differs depending on the topology. If the wrong components are selected, the required specifications cannot be met and the circuit design must be redone. The topology selection page provided by ROHM guides you through the selection of the best device for different topologies.

Flexible lines

ROHM Apollo’s Hirokawa Factory in Fukuoka Prefecture began operating a new semiconductor back-end process line. Sample production for sales expansion started April 2021. The following year, in 2022, we began mass producing discrete products. The clean room, which embodies the concept of an ‘unmanned high-mix production line’ features a compact design using three sets of equipment neatly arranged in a U-shape with AGVs (Automated Guided Vehicles) running between them. Technicians monitor the status of all lines via monitors in an adjacent control room.
