Overview
Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency, Low Noise and Low Standby Power in Full Load Range STR-Y6453 Sep, 2013 ◆General Descriptions The STR-Y6453 is power IC for quasi-resonant switching type power supplies, incorporating a power MOSFET and a controller IC.
The product is automatically switched to the quasi resonant operation, one bottom skip quasi resonant operation and two bottom skip operation in normal operation, and to the burst oscillation operation in light load.
That realizes the low standby power and a power supply system with high cost performance, low external part count can be easily composed.
◆Package Package name: TO-220F-7L (FMS207) ◆Features  Multi operation mode 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 range of loads.
 Current mode control method  The built-in startup circuit reduces the power consumption  Auto burst oscillation operation reduces dissipation.
Input power PIN ≤ 0.
1W at no load  Standby input compensation  Overcurrent protection with AC input compensation function  Built-in soft start function  Built-in maximum on-time limitation circuit  Built-in leading edge blanking function  Avalanche energy guaranteed; two-chip structure (enabling the simplification of surge absorbing circuit)  Protection functions Overcurrent protection (OCP) with input compensation function: pulse by pulse basis, low dependence on input voltage Overload protection (OLP); latched shutdown or auto restart Overvoltage protection (OVP); latched shutdown ◆Application Switching Power Supplies for  Digital appliance such as BD/DVD recorder, FPD TVs, etc.
 OA equipments such as printer  Home appliance (white goods)  Industry Machines  Communication Devices ◆Specification MOSFET 650V, 1.
8Ω(MAX) ◆Typical application circuit Sanken Electric Co.
