Package Package nam

Overview

Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency and Low Noise in Full Load Range STR-W6765N.

Key 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.
