Description

The UC3842B, UC3843B series are high performance fixed frequency current mode controllers. They are specifically designed for. Off Line and DC DC The fundamental challenge of power supply design is to simultaneously realize two conflicting objecti- ves : good electrical performance and low cost. The. Much attention has been given to the Single Ended. Primary Inductor Converter ( SEPIC) topology re- cently because output voltage may be either higher.
