• Protection Functions:

▫ Overcurrent Protection function (OCP); Pulse-by-pulse,

built-in compensation circuit to minimize OCP point variation

on AC input voltage

▫ Overload Protection function (OLP); Auto restart, built-in

timer, reduces heat during overload condition, and no external

components required

▫ Overvoltage Protection function (OVP); Auto restart

▫ Thermal Shutdown function (TSD); Auto restart

*The listed output power is based on the package thermal ratings, and the peak

output power can be 120% to 140% of the value stated here. At low output voltage

and short duty cycle, the output power may be less than the value stated here.
