Description  
Frequency jittering for low EMC  
The device is an off-line converter with an 800 V  
rugged power section, a PWM control, two levels  
of over-current protection, over-voltage and  
overload protections, hysteretic thermal  
Output overvoltage protection  
High primary current protection (2nd OCP)  
Extra power timer for peak current  
protection, soft-start and safe auto-restart after  
any fault condition removal. Burst mode operation  
and device very low consumption help to meet the  
standby energy saving regulations. Advance  
frequency jittering reduces EMI filter cost. The  
extra power timer allows the management of  
output peak power for a designed time window.
