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 solution 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 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 anddevices). 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 negotiations 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 TUSB8041 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. This device expands the USB Type-C host signals to four ports, which allowssimultaneous USB 3.0 or USB 2.0 enumeration at the Type-C and Type-A receptacle ports. This devicealso enables the USB Type-C plug to utilize the USB 2.0 low-speed endpoint feature of the TPS65983B.

The power path between the USB Type-C plug and receptacle ports is controlled by the LM3489 variableDC-DC converter. The TPS65983B device controls the output voltage of the LM3489 device, dependingon the power contract that is negotiated with the USB Type-C host. This feature is particularly useful whenthere is a mismatch in power contracts between a USB Type-C host and charger.

Both USB Type-C interfaces utilize the TPS83S00 and TPD1E01B04 electrostatic discharge (ESD)devices for signal input-output (I/O) protection. The USB Type-A interface uses single-bit ESD(TPD1E01B04) for I/O protection. The HDMI interface is protected using the TPD13S523, which is anintegrated 13-channel ESD and current-limiting device.
