1.89 MB

Description:

Fixed Frequency Controller

Features

* a timer
* based fault detection that ensures the detection of 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 very low

Applications

* AC
* DC Adapters for Notebooks, LCD, and Printers
* 10 ms Soft
* Start
* Offline Battery Chargers
* Internal Thermal Shutdown
* Consumer Electronic Power Supplies
* No
* Load Standby Power < 30 mW
* Auxiliary/Housekeep
