STR-W605XS

Current Mode Control PWM Regulator IC For Switching Power Supplies

Sanken Electric co.,ltd. 

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
