STRW6765N - Sanken

STRW6765N Power IC for Quasi-Resonant Type Switching Power Supply

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 mo.

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 voltag.
