STR3A161HD, STR3A162HD,
STR3A163HD
PWM Off-Line Switching Regulator ICs
Features and Benefits (continued)
• Soft Start function: reduces stress on internal power MOSFET
and secondary output rectifier diode at startup
• 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 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.
