NCP1244 Fixed Frequency Controller

NCP1244 Description

NCP1244 Fixed Frequency Current Mode Controller for Flyback Converters The NCP1244 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.

NCP1244 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

* 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
