1、基于TIDA-03027的USB Type-C多端口适配器电源参考设计TI公司的TIDA-03027是USB Type-C和供电多端口适配器电源参考设计,包括USB Type-C全特性的插座,可即时连接USB Type-C充电器(高达20V/3A)或设备。也可连接到HDMI 2.0和USB3.0 Type-A接口,主要用在笔记本电脑,平板电脑和带USB Type-C接口的电话系统。本文介绍了参考设计TIDA-03027主要特性,生态系统图和框图,电路图,材料清单和PCB设计图。The TIDA-03027 reference design offers a multiportadapter s
2、olution that enables products with a USBType-C interface to connect to HDMI 2.0 and USB3.0 Type-A interfaces. The design also includes anadditional USB Type-C full-feature receptacle, whichallows the user to simultaneously connect USB Type-C chargers (up to 20 V, 3 A) or devices. This featureset is
3、particularly useful as a peripheral to notebook,tablet, and phone systems with a single USB Type-Cinterface.The TIDA-03027 reference design showcases a Type-C plug that allows a notebook, tablet, or phone tosimultaneously interface with HDMI 2.0, USB 3.0 Type-A, and USB Type-C systems (chargers andd
4、evices)。 Thus, the board serves as a multiport adapter for USB Type-C hosts. This board features USB3.0 data, video, and charging (up to 20 V, 3 A) over a single, USB Type-C plug connection.The USB Type-C plug and receptacle both interface with a TPS65983B device, which handles powerdelivery negotia
5、tions and controls the primary power field-effect transistors (FETs)。 Two SuperSpeedlanes (SSTX/RX2) are routed directly to a DisplayPort (DP) to HDMI converter. The other SuperSpeedlanes (SSTX/RX1) are routed to the HD3SS3212, which demuxes the signals between the DP-to-HDMIconverter and the TUSB80
6、41 USB 3.0 HUB. This routing allows the TPS65983B device to controlbetween four-lanes of DP-to-HDMI and two-lanes of DP-to-HDMI + USB3.0 (for Type-A and Type-C dataconnections)。The TUSB8041 is a USB 3.0 HUB, which receives high-speed and SuperSpeed signals from the upstreamUSB Type-C plug.
