Between energy efficiency regulations and IEC requirements for improved 
power factor, linear supplies with iron core transformers are not 
attractive alternatives for most products. Besides that, increasing 
costs of copper and transformer-grade iron makes a switcher cost 
effective at lower power levels than before. Line frequency transformers 
now are rare in consumer products.
