More and more power adapters are migrating to USB type-C .
The smartphone industry has well defined players such as Apple, Google, Samsung, and others. Most if not every phone ships with a power adapter in the box.
It is well known that power adapters continue to burn power even when not in use. This is commonly referred to as no-load power consumption. Regulators continue to drive down this no-load power consumption of power adapters. Regulators include: USA EPA, EU CoC, and China MII.
Major semiconductor designers are obligated to constantly reduce the no-load consumption to fulfill these regulatory requirements.
We have designed and produced a novel USB type-C power adapter that reduces this no-load power consumption to zero!
Looking back, our good friend had returned from Europe to share adventures and encourage new opportunities. This discussion revolved around power efficiency rules around those little power adapters everybody uses to charge their phones, and that most just take for granted. The requirements were tightening again. The portion of the specification regarding the no-load power consumption caught our attention.
For those that do not already know, "no-load" is a term used to describe how much energy is consumed (or more precisely wasted) when the power adapter is not attached to a phone, and just waiting around in standby, sleep, or a nearly off-state, until a phone is attached.
The European Commission has a regulatory group that publishes a Code of Conduct, CoC, which expresses a variety of efficiency limits, was once again tightening the noose around no-load consumption, driving it even lower. Someone in the group confidently stated, "Hey, why not just drive it to zero?" Our euro-buddy responded, "Can you do that?…This is genius!" And thus the early genesis of a Prosary project was conceived.
