CIRCUIT DESCRIPTION  
The MagI³C Power Modules 1779205x1 are based on a push pull converter with integrated Transistors, rectifying diodes,  
isolated transformer, input and output capacitors. The modules are unregulated.  
Since there is no feedback path from the output to the input, the duty cycle is fixed to 50%. The duty cycle is independent  
from the load (zero load to full load). The output voltage is basically defined by the turns ratio of the transformer.  
PROTECTIVE FEATURES  
Due to the structure of the MagI3C Power Module following protective feature are NOT implemented:  
Over temperature protection (OTP)  
Over current protection (OCP)  
Output overvoltage protection (OVP)  
Input overvoltage protection  
Short circuit protection (SCP)  
Input reverse polarity protection  
Note: To protect the source and the MagI3C Power Module in abnormal conditions (secondary side overload or short circuit)  
a primary side input fuse of max. 1A (slow blow) is recommended.
