STR-W6251D,
STR-W6252D, and
STR-W6253D
PWM Off-Line Switching Regulator ICs
Features and Benefits (continued)
▪ Built-in startup circuit: reduces power consumption in standby
operation, and eliminates external components
▪ Bias-Assist function: improves startup operation, suppresses
VCC pin voltage drop in operation, and allows use of smaller
VCC capacitor
▪ Built-in Leading Edge Blanking function
▪ 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 few
external components required
▫ External Latch Protection function (ELP): latched shutdown
by external signal
▫ Overvoltage Protection function (OVP): latched shutdown
▫ Thermal Shutdown function (TSD); latched shutdown

*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.
