Power IC for Quasi-Resonant Type Switching Power Supply

Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency and Low Noise in Full Load Range STR-W6765N ◆General description The STR-W6765N is power IC for quasi-resonant type switching power supply, incorporating a power MOSFET and a controller IC. The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation and the bottom-skip quasi-resonant operation. ◆Package Package name: TO-220F-6L (FM207) Sep. 2013 ◆Features  Multi operation mode The operation mode switching according to load conditions achieves the optimal high efficiency and low noise power supply systems across the full load range.  Current mode control  Built-in PWM oscillator The PWM operates with the minimum frequency of around 22kHz, until the quasi-resonant signal becomes valid, reduces the stress on components at startup and load-shorted.  Built-in soft start function  Step-drive function, reducing switching noise  Input compensation at overcurrent The function reduces the distortion of overcurrent operation point to AC input voltage change by adding three components.  Avalanche energy guaranteed by two chips structure (Simplification of surge absorbing circuit)  Protection functions Overcurrent protection (OCP); Pulse-by-pulse Overload protection (OLP); latched shutdown Overvoltage protection (OVP); latched shutdown ◆Specification MOSFET 800V(MIN), 1.8Ω(MAX) ◆Applications Switching power supplies for  LCD-TVs, PDP-TVs, CRT-TVs and Di.
