Overview
NCP1247
Fixed Frequency Current Mode Controller for Flyback Converters
The NCP1247 is a new fixed−frequency current−mode controller featuring the Dynamic Self−Supply.
This function greatly simplifies the design of the auxiliary supply and the VCC capacitor by activating the internal startup current source to supply the controller during start−up, transients, latch, stand−by etc.
This device contains a special HV detector which detect the application unplug from the AC input line and triggers the X2 discharge current.
This HV structure allows the brown−out detection as well.
It features a timer−based fault detection that ensures the detection of overload and an adjustable compensation to he...
