VIPER17  
Off-line high voltage converters  
Features  
800 V avalanche rugged power section  
PWM operation with frequency jittering for low  
EMI  
SO16 narrow  
DIP-7  
Operating frequency:  
– 60 kHz for L type  
– 115 kHz for H type  
Description  
Standby power < 50 mW at 265 Vac  
Limiting current with adjustable set point  
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  
protection, soft-start and safe auto-restart after  
any fault condition removal. Burst mode operation  
and device very low consumption helps to meet  
the standby energy saving regulations.  
Adjustable and accurate over voltage  
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  
Adapters for PDA, camcorders, shavers,  
cellular phones, videogames  
Auxiliary power supply for LCD/PDP TV,  
monitors, audio systems, computer, industrial  
systems
