VIPER25  
Off-line high voltage converters  
Features  
800 V avalanche rugged power section  
Quasi-resonant (QR) control for valley  
switching operation  
SO16 narrow  
DIP-7  
Standby power < 50 mW at 265 Vac  
Limiting current with adjustable set point  
Description  
Adjustable and accurate overvoltage  
protection  
The device is an off-line converter with an 800 V  
rugged power section, a PWM control, double  
levels of overcurrent protection, overvoltage and  
overload protections, hysteretic thermal  
On-board soft-start  
Safe auto-restart after a fault condition  
Hysteretic thermal shutdown  
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. The quasi-  
resonant feature reduces EMI filter cost. Brown-  
out and brown-in 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.  
Applications  
Adapters for PDA, camcorders, shavers,  
cellular phones, cordless phones, videogames  
Auxiliary power supply for LCD/PDP TV,  
monitors, audio systems, computer, industrial  
systems, LED driver, No el-cap LED driver,  
utility power meter  
SMPS for set-top boxes, DVD players and
