Operating frequency:  
– 60 kHz for L type  
– 115 kHz for H type  
Description  
Standby power < 50 mW at 265 Vac  
The device is an off-line converter with an 800 V  
rugged power section, a PWM control, two levels  
of over-current protection, overvoltage and  
overload protections, hysteretic thermal  
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.  
Limiting current with adjustable set point  
Adjustable and accurate overvoltage  
protection  
On-board soft-start  
Safe auto-restart after a fault condition  
Hysteretic thermal shutdown  
Advance frequency jittering reduces EMI filter  
cost. Brown-out function protects the switch mode  
power supply when the rectified input voltage  
level is below the normal minimum level specified  
for the system. The high voltage start-up circuit is  
embedded in the device.  
Application  
Auxiliary power supply for consumer and home  
equipments  
ATX auxiliary power supply
