VIPER16LD General Description

The device 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. 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 devices very low consumption both help to meet the standard set by energy saving regulations.Ultra wide range dual output buck converter base.16 V-280 mA non isolated off-line high voltage c.4 W non-insulated, wide input voltage range SMPS.Triac and AC switch insulated control evaluation.1.5 W double output buck demonstration board bas.Wide range isolated flyback demonstration board,.
