Author:Robert Bielby

This paper describes a new family of integrated switchers that build on the simplicity of switchers like TOPSwitch but add numerous features without the associated cost. It describes a family of devices that incorporate soft-start, under-voltage lock-out, over-voltage lockout, external current limit, frequency jitter and other features, all incorporated into a single 5-pin package.
