Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency and Low Noise in Full Load Range STR-X6750F Sep. 2013 ◆General description The STR-X6750F 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. ◆Features Quasi-resonant operation mode Achieves the optimal high efficiency and low noise power supply systems. 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 guarante […]
