NCP12400 - Fixed Frequency Current-Mode Controller

Pin # Pin Name

Fixed Frequency Current Mode Controller for Flyback Converters NCP12400 The NCP12400 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 detects the application unplug from the ac input line and triggers

NCP12400 Features

* a timer-based 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
