Description

This is 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-X6756 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 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 overcurr.
