TI公司的TIDA-03027是USB Type-C和供電多端口適配器電源參考設計，包括USB Type-C全特性的插座，可即時連接USB Type-C充電器（高達20V/3A）或設備。也可連接到HDMI 2.0和USB3.0 Type-A接口，主要用在筆記本電腦，平板電腦和帶USB Type-C接口的電話系統。本文介紹了參考設計TIDA-03027主要特性，生態系統圖和框圖，電路圖，材料清單和PCB設計圖。

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.
