NOTE: The main regulated output is the 5.0 VDC at 3 Amperes. The other outputs are regulated by virtue of being wound on the same transformer, therefore are termed "cross regulated". Since the cross-regulated outputs do not have a linear (dissipative) regulator, the converter is more efficient and can deliver higher overall power than a corresponding linear post-regulated converter.
