Description

The TOP224PN is a 30W 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.
Very low AC/DC losses up to 90% efficiency
Built-in auto-restart and current limiting
Latching thermal shutdown for system level protection
Works with primary or opto feedback
Stable in discontinuous or continuous conduction mode
Source connected tab for low EMI
Circuit simplicity and design tools reduce time to market
