Overview
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,...
