VIPerPlus family: Fixed frequency 12W high performance off line high voltage converter

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.

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.

Key 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 overvoltage protection
  • On-board soft-start
  • Safe auto-restart after a fault condition
  • Hysteretic thermal shutdown
