NCP1225
feature can help the end products to ply with immediate and future international power saving regulations easily. An innovative feedback pensation scheme is integrated in NCP1225 to eliminate the expensive optocoupler in the feedback path. By only using simple auxiliary winding feedback, the regulator still can achieve good output voltage regulation usually not possible with mon SMPS controller ICs without optocoupler. For even better regulation applications, optocoupler feedback can still be used in place. Additionally, value- added features as overvoltage protection, undervoltage lockout...
