Operating Description The MC34262, MC33262 contain many of the building blocks and protection features that are employed in modern high performance current mode power supply controllers. There are, however, two areas where there is a major difference when compared to ...

A significant reduction in line current distortion can be attained by forcing the preconverter to switch as the ac line voltage crosses through zero. The forced switching is achieved by adding a controlled amount of offset to the Multiplier and ...

A Quickstart circuit has been incorporated to optimize converter startup. During initial startup, compensation capacitor C will be discharged, holding the error amp 1 output below the Multiplier threshold. This will prevent Drive Output switching and delay bootstrapping of capacitor ...
