"The STR- X6769B 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.

â—†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, reducing the stress on components at startup and load-shorting.
-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 guaranteed by two chips structure (Simplification of surge absorbing circuit) -Protection functions:
Overcurrent protection (OCP); Pulse-by-pulse
Overload protection (OLP); latched shutdown
Overvoltage protection (OVP); latched shutdown
