Power Integrations TOP258PN High Side 1, Off Liner Power Switch IC 8-Pin, DIP-C

The TOPSwitch-HX is a highly integrated monolithic off-line switcher IC designed for off-line power supplies. TOPSwitch-HX integrated circuits enable design of power supplies up to 195 W, while providing high efficiency under all load conditions. TOPSwitch-HX also provides very good performance at low load and during standby (no load) operation.

• Multi-mode operation maximizes efficiency at all loads
• No heatsink required up to 35 W (up to 48 W at 230 VAC) using P, G or M packages
• Output overvoltage protection (OVP)
• Line undervoltage (UV) detection prevents turn-off glitches
• Line overvoltage (OV) shutdown extends line surge limit
• Accurate programmable current limit
• Optimized line feed-forward for line ripple rejection
• Fully integrated soft-start for minimum start-up stress
• Energy efficient over entire load range
• No-load consumption
