Profile: Cambridge Semiconductor Ltd. is a semiconductor company. We are certified with ISO 9001 certification. We are determined to develop new power integrated circuits. Our products are subjective to power supplies and lighting products manufacturing industries. Our range of RDFC controllers consist of common features like highly integrated CMOS controller IC, bipolar power transistors driven, resonant switching for high efficiency and low emissions, optimized frequency for power circuit parasitics, IC protection for overload, over-temperature & under voltage. On the other side PSS controllers we provide are unique in combining primary side sensing, current regulation and no-load power consumption.
