Fixed Frequency Controllers
Low Cost and Low Power Consumption. . .
Fixed frequency controllers from ON Semiconductor are the perfect solution for many applications. DVD
players, set-top boxes, notebook power adapters, printers, scanners, LCD monitors, and a wealth of other end
products use our controllers. Extremely low standby power helps you easily meet applicable regulations. The
Dynamic Self-Supply (DSS) feature of our devices saves cost by avoiding the use of an auxiliary transformer
winding, and current-mode topologies give tighter control of output voltage. Our fixed frequency controllers
can help you meet your toughest design challenges while still keeping cost to a minimum.
