Description
General part information
TOP221 Series
The TOP221PN is a 9W second generation 3-terminal Off-Line PWM Switch provides several enhancements over the first generation TOPSwitch family. Many significant circuit enhancements that reduce the sensitivity to board layout and line transients now make the design even easier. TOPSwitch incorporates all functions necessary for a switched mode control system into a three terminal monolithic IC are power MOSFET, PWM controller, high voltage start up circuit, loop compensation and fault protection circuitry.
