EVLVIPER28L-10W

EVLVIPER28L-10W is a isolated flyback PSU using VIPER28HN. This device is an off line converter with an 800V rugged power section, a PWM control, two levels of overcurrent protection, overvoltage and overload protections, hysteretic thermal protection, softstart and safe auto restart after any fault condition removal. Burst mode operation and device very low consumption help to meet the standby energy saving regulations. Advance frequency jittering reduces EMI filter cost. The extra power timer allows the designer to fix the maximum time window during which the converter is able to manage the peak power and still maintain output voltage regulation. If the overload lasts for longer than this time window, the converter is automatically shut down and enters auto restart mode until the overload is removed, so as to prevent damage to the power components.
