NCP1248 Fixed Frequency Current Mode Controller for Flyback Converters The NCP1248 is a new fixed-frequency current-mode controller featuring the Dynamic Self-Supply. This function greatly simplifies http://onsemi.com 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 SOIC−7 line and triggers the X2 discharge current. This HV structure allows CASE 751U the brown-out detection as well.
