VIPER28

VIPerPlus family: fixed frequency high performance off line high voltage converter
  • active Active

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 help to meet the standby energy saving regulations. Advance frequency jittering reduces EMI filter cost. The extra power timer allows the management of output peak power for a designed time window.

The high voltage start-up circuit is embedded in the device.
