SCY99194  
Fixed Frequency Current  
Mode Controller for Flyback  
Converters  
The SCY99194 is a new fixed−frequency current−mode controller  
featuring the Dynamic Self−Supply. This function greatly simplifies  
http://onsemi.com  
MARKING  
the design of the auxiliary supply and the V capacitor by activating  
CC  
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.  
It 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 power consumption. Internal frequency jittering, ramp  
compensation, and a versatile latch input make this controller an  
excellent candidate for the robust power supply designs.  
A dedicated Off mode allows to reach the extremely low no load  
input power consumption via “sleeping” whole device and thus  
minimize the power consumption of the control circuitry.
