■ General Descriptions
The STR-W6700 series products are power ICs for quasi-resonant type switching power supplies, 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. The STR-X6700 series products are the different package (TO-3PF) versions.

■ Features
• Multi-Mode Control
   The operation mode switching with three steps according to load conditions achieves the optimal high efficiency and low noise power supply systems across the full load range. (The confirmation of product number is necessary because some functions are different in each product.)
   • In Standby (Under Standby Load Conditions):
      -UVLO Intermittent Oscillation by lowering output voltage --- Switched by Standby Signal, or
      -Auto Burst-Oscillation --- Switched Automatically
   • Under Low to Middle Load Conditions: Bottom-Skip Quasi-Resonant Operation
      (Bottom-Skip QR)
   • Under Middle to Rating (or Heavy) Load Conditions: Quasi-Resonant Operation (QR)
• Current-Mode Control
• Built-in PWM Oscillator
   The PWM operates with the minimum frequency of around 22 kHz, until the quasi-resonant
   signal becomes valid, reduces the stress on components at startup and load-shorted.
• Soft-Start Function
• Step-Drive Function, reducing switching noise
• Built-in Maximum ON Time Limitation Circuit The function limits the maximum ON time of power
   MOSFET, during the transitions at low input voltage, power ON/OFF.
• Input Compensation at Overcurrent The function reduces the distortion of overcurrent operation
   point to AC input voltage change by adding three components.
• Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET
• Various Protections
   Overcurrent Protection (OCP) -------------------------------- Pulse-by-Pulse
   Overload Protection (OLP)-------------------------------------- Latch Shutdown
   Overvoltage Protection (OVP) -------------------------------- Latch Shutdown

■ Applications
   Switching Power Supplies for Digital Consumer Equipment;
      LCD-TVs, PDP-TVs, CRT-TVs, etc., Home Appliances, OA Equipments,
      Industry Machines, Communication Devices, Others
