General Descriptions
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.
components.
Features
Applications
Product Lineup
The product easily achieves high cost-performance power supply systems with few external
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
Soft-ON Function, preventing the audible noise from transformer at standby (Burst-Oscillation)
Built-in Soft-Start Function
Built-in Bias Assist Function
Overcurrent Protection (OCP) with AC Input Compensation Function
Built-in Leading Edge Blanking Function
Built-in High-Voltage Power MOSFET with Avalanche Energy Guaranteed
Protection Functions
