Overview
Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency and Low Noise in Full Load Range STR-W6723N ◆General description The STR-W6723N is power IC for quasi-resonant type switching power supply, incorporating a power MOSFET and a controller IC.
The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation and the bottom-skip quasi-resonant operation.
◆Package Package name: TO-220F-6L (FM207) Sep.
2013 ◆Features  Multi operation mode The operation mode switching according to load conditions achieves the optimal high efficiency and low noise power supply systems across the full load range.
 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 450V(MIN), 1.
4Ω(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 STR-W6700 D 1 VCC 4 3 S/GND ROCP Cont 7 OCP /BD 6 FB 5 SS /OLP RX CX P S1 +B ErrAmp D S2 GND Standby ON/OFF LowB SI Standby Out ERrreAgm:pS：SaAnNkKeEnN　lSinE　eSaerriersegulator, etc.
