NCP1240 - Fixed Frequency Current-Mode Controller

NCP1240 Description

NCP1240 Fixed Frequency Current Mode Controller for Flyback Converters The NCP1240 is a new fixed *frequency current *mode controller .
Pin No Pin Name Function 1 LATCH Latch. Off Input 2 FB Feedback + Shutdown pin 3 CS Current Sense 4 GND 5 DRV 6 VCC. Drive ou.

NCP1240 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

NCP1240 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
