Power Supply Not complying with the new DOE Level VI Performance Requirements
Power Supply Not complying with the new DOE Level VI Performance Requirements
(OP)
I'm working on a VERY custom 120VAC to 5VDC power supply and I've looked over the new DOE efficiency standards and I've noticed that they have changed the Max power in the No Load mode to 100mW for my power output. Given the complex design of the power supply I do not think that I can meet this condition at this time. What are the repercussions of not meeting the DOE efficiency standards? I would still like to get this power adapter UL certified so I'm hoping this won't be a problem there either. Any insight would be helpful!

You realize there are 1 and 1/2W isolated supplies that have 5kV isolation and come in SMD footprints?

Will the cost of each wall-wart go up by more than 26 cents to get the extra circuitry in there?
Did the government get input from major suppliers of such devices for their opinion as to what this extra cost will be?
