STR-Y6400 Series
Power IC for Quasi-Resonant Type Switching Power Supply
with High Efficiency, Low Noise and Low Standby Power
in Full Load Range
■ General Descriptions
The STR-Y6400 series products are power ICs for quasi-resonant switching type power
supplies, incorporating a power MOSFET and a controller IC. The product achieves high
efficiency and low noise power supply systems across the full load range, by the low standby
power, the quasi-resonant operation, the bottom-skip quasi-resonant operation, and the
burst-oscillation.
The STR-L6400 series products are the different package (SIP-10) versions.
■ Features
TO-220F-7
Multi-Mode Control
The operation mode switching with four steps according to load conditions achieves the optimal high efficiency and
low noise power supply systems across the full load range.
・In Standby: Auto Standby (Auto Burst-Oscillation)
・Under Low to Middle Load Conditions: 1 or 2 Bottom-Skip Quasi-Resonant Operation (Bottom-Skip QR)
・Under Middle to Rating (or Heavy) Load Conditions: Quasi-Resonant Operation (QR)
Current-Mode Control
Bottom-Skip Function with Delay Time Setting, enabling stable switching
Built-in Startup Circuit, enabling low power consumption
Auto-Standby Function with Burst-Oscillation, enabling low standby power(Input power PIN < 100mW at no load)
Soft-ON Function, preventing the audible noise from transformer, during the standby operation (burst-oscillation)
and the dynamic load change.
Soft-Start Function
Step-Drive Function, reducing switching noise
Leading Edge Blanking Function
External ON/OFF Function
Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET
Various Protections
Overcurrent Protection (OCP)-------- Pulse-by-Pulse with AC Input Compensation Function
Overload Protection (OLP) ----------- Latch Shutdown or Auto-Restart Option by changing external components
Overvoltage Protection (OVP) ------- Latch Shutdown
■ Applications
Switching Power Supplies for
Digital Consumer Equipment; LCD-TVs, BD/DVD Players/Recorders, etc., Home Appliance (White Goods),
OA Equipments, Industry Machines, Communication Devices, Others
