Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency and Low Noise in Full Load Range Sep. 2013 - General description The STR- X6756 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. - 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 22k Hz, until the quasi-resonant signal bees valid, reduces the stress on ponents at startup and load-shorted. - Built-in soft start function - Step-drive function, reducing switching noise - Input pensation at overcurrent The function reduces the distortion of overcurrent operation point to AC input voltage change by adding three ponents. - 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 - Package Package name: TO-3PF-7L - Specification MOSFET 650V(MIN), 0.73Ω(MAX) - Application Switching power supplies for - LCD-TVs, PDP-TVs, CRT-TVs and Digital consumer equipment - Home appliances - OA equipments - Industry machines - munication devices - Typical application circuit STR-X6700 D...
