Description

The VIPER06 is an offline converter with an 800 V

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.
