VIPER06LSTR

VIPER06LSTR is an energy saving high voltage converter for direct feedback. This is an offline converter with an 800V avalanche rugged power section, a PWM controller, a user-defined overcurrent limit, open-loop failure protection, hysteretic thermal protection, soft startup and safe auto-restart after any fault condition. The device is able to power itself directly from the rectified mains, eliminating the need for an auxiliary bias winding. Advanced frequency jittering reduces EMI filter cost. Burst mode operation and the device’s very low power consumption both help to meet the standards set by energy-saving regulations. Typical applications include replacement of capacitive power supplies, home appliances, power metering and LED drivers.
