Features

* a timer-based fault detection that ensures the detection of MARKING DIAGRAM overload and an adjustable compensation to help keep the maximum power independent of the input voltage. Due to frequency foldback, the controller exhibits excellent efficiency in light load condition while still achieving

Applications

* 10 ms Soft-Start
* AC-DC Adapters for Notebooks, LCD, and Printers
* Internal Thermal Shutdown
* Offline Battery Chargers
* No-Load Standby Power < 30 mW
* Consumer Electronic Power Supplies
* X2 Capacitor in EMI Filter Discharging Fea
