The VIPER27LD is an offline High Voltage Converter with an 800V 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. Advance frequency jittering reduces EMI filter. 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.
● PWM operation with frequency jittering for low EMI
● Limiting current with adjustable set point
● Adjustable and accurate overvoltage protection
● Safe auto-restart after a fault condition
● Hysteretic thermal shutdown
● 60kHz Operating frequency
