STR-Y6700 ■ General Descriptions Series Power IC for Quasi-Resonant Mode Switching Power Supplies with Low Standby Power, High Efficiency and Low Noise in Full Load Range 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. ■ Features TO-220F (FMY207) Multi-Mode Control The automatic operation mode switching with three steps according to load conditions achieves the optimal power supply systems with high efficiency and low noise across full load range. ·In Standby------------------------------------------------------ Auto Standby Operation ( Burst-Oscillation) ·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 Startup Circuit, enabling Low Power Consumption Auto-Standby Function with burst-oscillation, enabling low standby power Input Power at no load : PIN < 30mW (100VAC), PIN < 50mW (240VAC) Soft-ON Function, preventing the audible noise from transformer at standby (Burst-Oscillation) Built-in Soft-Start Fun……
