Datasheet Details

Part number:

NCP1240

Manufacturer:

ON Semiconductor ↗

File Size:

1.80 MB

Description:

Fixed Frequency Current-Mode 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
* Offline Battery Chargers
* Consumer Electronic Power Supplies
* Auxiliary/Housekeeping Power Supplies
* Offline Adapters for Notebooks
* These Devices are Pb
* Free and Halogen Free/BFR
