ROHM Semiconductor has recently announced the development of power supply ICs for AC/DC converters in primary power supplies for home appliances and AC adapters. The BM2xxx/F series consists of 24 models that utilize a proprietary low ON resistance SJ MOSFET and feature circuit optimization, resulting in industry-leading efficiency and low noise. In addition, a surface mount type is available in the SOP8 package that contributes to set miniaturization. ROHM is working on expanding its lineup to achieve high efficiency in a wide range of home electronics, including appliances, TVs, and monitors.
