The STR-W6734 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 mod.
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 voltag.
