NCP1246 Fixed Frequency Controller

NCP1246 Description

NCP1246 Product Preview Fixed Frequency Current Mode Controller for Flyback Converters The NCP1246 is a new fixedïfrequency currentïmode controller fe.
Pin No 1 2 3 4 5 6 Pin Name LATCH FB CS GND DRV VCC Function LatchïOff Input Feedback + Shutdown pin Current Sense ï Drive output VCC input Pin Descri.

NCP1246 Features

* a timerïbased 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 standby

NCP1246 Applications

* Protection Sensing Input
* ACïDC Adapters for Notebooks, LCD, and Printers VCC Operation up to 28 V, With Overvoltage Detection
* Offline Battery Chargers 500/800 mA Source/Sink Drive Peak Current
* Consumer Electronic Power Supplies Capability
* Auxiliary/Housekeepin
