VIPER17
Off-line high voltage converters

Features
■ 800 V avalanche rugged power section
■ PWM operation with frequency jittering for low EMI
■ Operating frequency: – 60 kHz for L type – 115 kHz for H type
■ Standby power < 50 mW at 265 Vac
■ Limiting current with adjustable set point
■ Adjustable and accurate over voltage protection
■ On-board soft-start
■ Safe auto-restart after a fault condition
■ Hysteretic thermal shutdown

Application
■ Adapters for PDA, camcorders, shavers, cellular phones, videogames
■ Auxiliary power supply for LCD/PDP TV, monitors, audio systems, computer, industrial systems
■ SMPS for set-top boxes, DVD players and recorders, white goods

Description
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.
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.
