Supertex Inc HV9906

The HV9906 combines internally all the components required to operate directly from the rectified AC line with a feedback mechanism that eliminates filters & compensation components, and which can close the loop with feedback from a discontinuous waveform (eg. The HV9906 is capable of driving multiconverters, which have been shown to provide the best performance to component count trade off for wide conversion range applications like offline converters.
