www.ti.com User’s Guide TPS65988 Evaluation Module ABSTRACT This document is the user guide for the TPS65988 Evaluation Module (TPS65988EVM). The TPS65988EVM allows for evaluation of the TPS65988 IC as part of a stand-alone testing kit and for development and testing of USB Type-C and Power Delivery (PD) end products. Out of the box, the TPS65988EVM is configured to emulate a dual-port laptop computer. Both ports can be used to source or sink power, and both are dual-role ports (DRP) but only support data as a downstream-facing port (DFP) host. When different configurations are required to test your system, use the TPS65988 Application Configuration software tool to create a configuration or load a different configuration template (see Figure 1-1). The TPS65988EVM uses a control MUX (HD3SS3412) to route DisplayPort™ (DP) and a USB HUB (TUSB8020) to route USB signals to the appropriate port A or port A (port A/B). The control MUX and USB HUB are connected to a SuperSpeed (SS) MUX (TUSB546) which routes the appropriate DP lanes and USB 3.0 signals according to cable orientation and Alternate Mode selection. Figure 1-2 highlights these features. Figure 1-1.

These DC/DC converters produce the required voltage rails for full functionality of the EVM including power delivery, powering internal and external circuits, and so forth. These test points allow the user to verify the system supplies on the TPS65988EVM. LDO_1V8 is internally generated for internal circuitry. Use P3V3 to supply VIN_3V3 which then supplies LDO_3V3. Also, use LDO_3V3 as a low-power output for external flash memory. In bus-powered conditions, or self-powered conditions, P3V3 and LDO_3V3 are active. P3V3 has the ability to operate at 4 V to compensate for IR drop through the USB Type-C cable. The P5V supply can operate at 4.5 V at 100% duty cycle, but it is intended to supply the 5 V at 3 A when the barrel jack or system power is connected to the EVM. P5V powers PP_CABLE for both ports as well as the VBUS current sense IC for both ports. Figure 5-27 highlights these test points. Figure 5-27.
