STR-W605xS
Current Mode Control PWM Regulator IC
For Switching Power Supplies
Features and Benefits (continued)
▪ Two-chip structure, with a controller and a power MOSFET
compensation circuit to minimize OCP point variation on
with guaranteed avalanche energy available to simplify surge
absorber circuits
▪ Protection functions:
▫ Brown-In and Brown-Out Protection function: auto-restart,
prevention of excess input current and heat rise at low
input voltage
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
▫ Overcurrent Protection function (OCP): pulse-by-pulse built-in ▫ Thermal Shutdown Protection 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.
