Beschreibung

The NCP1654 is a Power Factor Controller to efficiently drive Continuous Conduction Mode (CCM) step−up pre−converters. As shown by the ON Semiconductor application note AND8322, “Four Key Steps to Design a Continuous Conduction Mode PFC Stage Using the NCP1654”, which details the four key steps to design a NCP1654 driven PFC stage, this circuit represents a major leap towards compactness and ease of implementation. Housed in a SO−8 package, the circuit minimizes the external components count without sacrificing performance and flexibility. In particular, the NCP1654 integrates all the key protections to build robust PFC stages like an effective input power runaway clamping circuitry. When needed or wished, the NCP1654 also allows operation in Follower Boost mode(1) to drastically lower the pre−converter size and cost, in a straight−forward manner. For more information on this device, please refer to the ON Semiconductor data sheet NCP1654/D. The board illustrates the circuit capability to effectively drive a high power, universal line application.
