Product Summary

The STR-Y6700 series products are power ICs for quasi-resonant (QR) switching mode power supplies, incorporating a 

power MOSFET and a controller IC.The product achieves high efficiency and low noise  systems, by automatic switching of  

Auto-Standby operation under light load conditions, QR operation and Bottom-Skip QR operation in normal operation. 
The product easily achieves high cost-performance power supply systems with few external components.
