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
