AC/DC Converters Fixed Freq VIPer 800V 115kHz Plus

The device is an off-line converter with a 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. It is able to power itself directly from the rectified mains, eliminating the need for an auxiliary bias winding. Advance frequency jittering reduces EMI filter cost. Burst mode operation and the IC low consumption both help to meet the standard set by energy saving regulations.
