随着今年早些时候推出USB-Pd规范，它已经扩展了USB电缆的功能，现在可以为各种设备提供高功率。
提供5W~10W功率的现有解决方案现在可以利用这项技术进行扩展，最高可提供100W功率。
这使OEM能够添加以前无法实现的功能或功能。
随着客户为这些产品制定计划以利用新功能，半导体供应商正在发布满足USB-Pd电气要求的解决方案。
客户一直在努力解决的关键问题之一是USB-Pd功能适用于智能手机/平板电脑和笔记本电脑的生态环境。
智能手机/平板电脑的功耗通常较低，现在正在寻求扩大功率以适应智能充电功能。
更高功率的笔记本电脑适配器希望增加为智能手机/平板电脑等小型设备充电的功能。
随着第一款仅支持USB A / B连接器的USB-Pd规格的推出，支持智能手机/平板电脑和笔记本电脑的愿景尚不清楚。
现在随着新的USB-Pd C型连接器的发布，这开辟了新的机会。
新型C型连接器是可逆的，比目前使用的其他连接器薄得多。
这创建了一种物理连接器，对两种产品类型都更为理想。
新的C型电气连接也得到了简化，这将降低OEM的实施成本。
为了支持新的USB C型规范，安森美半导体是上周在华盛顿州西雅图举行的USB 3.1开发者日上首次展示全功能AC / DC适配器的公司。
该解决方案被强调为行业领导者聚集在一起快速向市场提供解决方案的一个很好的例子。
该解决方案是基于业界领先的PWM控制器NCP1247的100W AC / DC适配器，并集成了赛普拉斯半导体的USB端口控制器。
该演示展示了为智能手机/充电器供电，然后根据新规格改变输出电压/电流以为笔记本电脑供电的能力。

With the introduction of the USB-Pd specification earlier this year it has expanded the capability of the USB cable to now deliver high power to various devices.  Existing solutions that deliver 5W ~10W of power can now utilize this technology to scale up to deliver up to 100W.  This is enabling OEM’s the ability to add functionality or capability that wasn’t possible before.  As customers are putting plans in place for these products to take advantage of the new capability, semiconductor suppliers are releasing solutions which meet the USB-Pd electrical requirements.
One of the key questions customers have been struggling with is where USB-Pd capability fits into the ecology for smartphone/tablet and notebooks.  The smartphone/tablet has typically been lower power and is now looking to scale up in power to accommodate smart charging capability.  Notebook adapters which are higher power are looking to add the capability to charge smaller devices like smartphones/tablets.
With the introduction of the first USB-Pd spec which only had the capability to support USB A/B connectors the vision to support both smartphone/tablets and notebooks was unclear.  Now with the release of the new USB-Pd C-type connector this has opened up new opportunities.  The new C-type connector is reversible and is much thinner than other connectors used today.  This has created a physical connector that is more desirable to both product types.  The new C-type electrical connection is also simplified which will lower the cost of implementation to OEM’s.

In support of the new USB C-type specification ON Semiconductor was the first company to demonstrate a fully functional AC/DC adapter last week at the USB 3.1 Developers Days in Seattle, WA.  The solution was highlighted as a good example of industry leaders coming together to provide solutions quickly to the market.  The solution is a 100W AC/DC adapter based on the industry leading PWM Controller NCP1247 and incorporates a USB port controller from Cypress Semiconductor.  The demo showcased the ability to power a smartphone/charger and then change output voltage/current per the new specification to power a notebook.
