　　TI公司的TIDA-01627是USB Type-C PD 45W移动电源/充电宝参考设计,用来对笔记本电脑,手机或基于Type-C/PD设备进行充电,支持5V/3A,9V/3A,14.8V/2A,15V/3A和20V/2.25A,连接到USB PD源后能自动荡进行充电.本文介绍了参考设计TIDA-01627主要特性和指标,框图,电路图,材料清单和PCB设计图.

　　This power bank reference design offers highlyintegratedUSB Type-C™ power delivery (PD) forcharging notebooks. The key aspect of this design isto reduce the bill of materials (BOM) cost whilemaintaining the overall functionality.The designimplements unique considerations for reducingquiescent current and covers all the required aspects to guide users through the part selection and trade-offconsiderations.

　　For many, carrying multiple devices is a normal if not necessary part of daily life. The average user’sdependency on these gadgets continues to increase while the overall battery life is decreasing. Manyusers have no choice but to carry an alternate portable source of power to help recharge gadgets while onthe move. This reference design offers a power bank solution that can provide 45 W of power to charge a notebook while away from traditional power sources.This reference design has been built around two key components: TPS65987D and BQ25703A.

　　TPS65987D is the PD controller which controls all of the USB Type-C™ and PD negotiations, in additionto controlling the BQ25703A battery charger over I2C. This battery charger chip manages all the powerand battery charging. The chip also works as a reverse buck-boost to provide power in on-the-go (OTG)mode. TPD8S300 provides protection from electrostatic discharge (ESD) and VBUS to CC short and the TPS563200 generates 3.3 V from the battery to power the PD controller.

　　参考设计TIDA-01627主要特性:

　　• Supports 5 V at 3 A, 9 V at 3 A, 14.8 V at 2 A, 15 Vat 3 A, and 20 V at 2.25 A for Power Data Objects(PDOs)
