VIPER16LDTR Description
The VIPER16LDTR is an off-line converter with an 800 V avalanche ruggedness power section, a PWM controller, user-defined overcurrent limit, protection against feedback network disconnection, hysteretic thermal protection, soft start-up, and safe auto restart after any fault condition. The VIPER16LDTR is able to power itself directly from the rectified mains, eliminating the need for an auxiliary bias winding. Advance frequency jittering reduces EMI filter costs. Burst mode operation and the device's very low consumption both help to meet the standard set by energy-saving regulations.
