The NCP1681 Evaluation Board (EVB) demonstrates a Multi−Mode Totem Pole PFC application built using the NCP1681BA and capable of delivering 500 W across an input voltage range of 90 – 265 Vac.
NCP1681BA is intended for use in High Performance Computing, industrial power supplies, UHD power supplies, Telecom/5G power, and Cloud/Server power supplies. High efficiency provided by the TPFC topology reduces the volume of heatsinks and/or forced air required for thermal management of the PFC, enabling a higher density power supply design.
