NCP1234 Fixed Frequency Current Mode Controller

NCP1234 Description

NCP1234 Fixed Frequency Current Mode Controller for Flyback Converters The NCP1234 is a new fixed *frequency current *mode controller .
Pin No Pin Name Function 1 LATCH Latch. Off Input 2 FB 3 CS Feedback Current Sense 4 GND 5 DRV 6 VCC Drive output VCC input 8 HV High.

NCP1234 Features

* a timer
* based fault detection that ensures the detection of overload independently of an auxiliary winding, and an adjustable compensation to help keep the maximum power independent of the input voltage. Finally, due to a careful design, the precision of critical parameters is well controlle
