NCP1248 - Fixed Frequency Current Mode Controller

NCP1248 Description

NCP1248 Fixed Frequency Current Mode Controller for Flyback Converters The NCP1248 is a new fixed-frequency current-mode controller featuring the Dy.
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.

NCP1248 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

NCP1248 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
