Combining a compact, light-weight, low-profile, high-efficiency design with a low EMI spec, ADP Series of 60W ac adapters are for portable applications, such as notebook computers, medical and industrial instrumentation. The firm's proprietary soft-switched multi-resonant, zero-current switching topology is characterized by higher efficiency and lower conducted EMI than traditional designs. The use of integrated magnetic technology reduces leakage current without internal screens or bulky filtering.
