隔离式输出可调节的高频有源功率因数校正器UCC3857

UCC3857 for Isolated Boost PFC Controller with Regulating an Output Bus Voltage

UCC3857具有隔离式 Boost 升压功率因数校正器所需的全部功能。该变换器的优点是用变压器隔离原边与副边,使输出直流电压低于输入电压。它用单级功率处理即可实现 PFC 与降压(或升压)变换,在要求高效率、高密度、高性能应用时,UCC3857是一种理想的选择。

The UCC3857 provides all of the control function necessary for an Isolated Boost PFC Converter.These converters have the advantage of transformer isolation between primary and secondary,as well as an output bus voltage that is lower than the input voltage.By providing both power factor correction and down(or up) conversion in a single power processing stage,the UCC3857 is ideal for applications which require high efficiency,integration,and performance.
