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.
