2013 ◆Package Package name: TO-220F-6L (FM207) ◆Features  Quasi-resonant operation mode Achieves the optimal high efficiency and low noise power supply systems.
 Current mode control  Built-in PWM oscillator The PWM operates with the minimum frequency of around 22kHz, until the quasi-resonant signal becomes valid, reduces the stress on components at startup and load-shorted.
 Built-in soft start function  Step-drive function, reducing switching noise  Input compensation at overcurrent The function reduces the distortion of overcurrent operation point to AC input voltage change by adding three components.
 Avalanche energy guaranteed by two chips structure (Simplification of surge absorbing circuit)  Protection functions Overcurrent protection (OCP); Pulse-by-pulse Overload protection (OLP); latched shutdown Overvoltage protection (OVP); latched shutdown ◆Specification MOSFET 650V(MIN), 0.
73Ω(MAX) ◆Applications Switching power supplies for  LCD-TVs, PDP-TVs, CRT-TVs and Digital consumer equipment  Home appliances  OA equipments  Industry machines  Communication devices ◆Typical application circuit +B ErrAmp P S1 GND D 1 4 VCC D S2 Standby ON/OFF LowB Standby Out GND Reg SI STR-W6700 S/GND 3 7 Cont 6 ErrAmpSanken ：SANKEN　 SE　Series Reg: linear regulator IC etc.
