Product Summary

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. The viper16ldtr is used in Replacement of capacitive power supply, Auxiliary power supply for appliances, Power metering, LED drivers.
