Description

The second generation TOPSwitch?-II family is more cost

effective and provides several enhancements over the first

generation TOPSwitch family. The TOPSwitch-II family

extends the power range from 100W to 150W for 100/115/

230 VAC input and from 50W to 90W for 85-265 VAC universal

input. This brings TOPSwitch technology advantages

to many new applications, i.e. TV, Monitor, Audio amplifiers,

etc. Many significant circuit enhancements that reduce the

sensitivity to board layout and line transients now make the

design even easier. The standard 8L PDIP package option
