The STR-W6200D series products are power ICs for switching power supplies,
incorporating a power MOSFET and a current-mode type PWM controller IC. The low
standby power is accomplished by the automatic switching between the PWM operation in
normal operation and the burst-oscillation under light load condition. The product achieves
high cost-performance power supply systems with few external components.

Home Appliances (White Goods), Digital Consumer Equipment, OA Equipment, Industry Machines,
Communication Devices, Others
Current-Mode Type PWM Control
PWM with Jittering Function
The function reduces the EMI noise and enables simplified (low-cost) EMI filters.
The jittering period is adjustable by an external capacitor.
Auto-Standby Function
The burst-oscillation enables the low standby power.
Input Power P
Built-in Startup Circuit, enabling low power consumption
Overcurrent Protection (OCP) with Built-in Input Compensation Circuit
The function has less AC input voltage dependency.
Overload Protection (OLP) with Built-in Delay Timer ( the delay time is adjustable by an external capacitor)
External Latch Protection (ELP)
The function enables the latch shutdown by external signal.
Bias-Assist Function, reducing operating V
The function improves the startup operation and makes a low V
Leading Edge Blanking Function
Slope Compensation Function
Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET
Various Protections
