An automotive voltage range input is applied at the J3 connector. The input stage consists of an input switch (Q1), protection (D2), and an input filter (L1, C1, C2, C3, C5). The voltage at the 5VDC node is regulated by the LM53603AQ buck regulator (U1) and associated circuitry. This provides a nominal 5-V, 3-A output for the TPS2549-Q1 (U2). The TPS2549-Q1 internal power switch connects the 5VDC node to VBUS at the downstream facing USB connector, J1. When the internal power switch is ON, the D5 LED (green) will illuminate. USB 2.0 data can be passed through the TPS2549Q1EVM-729 from J2 to J1 when the TPS2549-Q1 is configured for either SDP or CDP mode using the J6 header. TPS2549-Q1 status and fault conditions can be detected using the D4 (blue) and D3 (red) LEDs, respectively. TPS2549-Q1 provides system-level ESD protection in accordance with IEC 61000-4-2 up to ±8-kV contact and ±15-kV air discharge at the DP_IN and DM_IN signals going to J1. These pins will also provide detection of shorts to VBUS by triggering the FAULT logic and illuminating D3. The TPS2549-Q1 provides USB cable voltage-droop compensation at the load through the use of the CS pin. Sinking current into the CS pin mirrors the current through the TPS2549-Q1 power switch at a rate of 75 µA/A. The CS pin current is summed with the LM53603AQ regulator feedback current through R8 causing the regulator output voltage to change with USB downstream load current. The voltage at the 5VDC node increases linearly as load current increases. This compensation will keep the load end voltage close to 5 VDC. The default compensation resistor values (R8 and R10) target a USB cable resistance of 200 mΩ. Three additional cable resistance examples are provided in the following list. • For 300-mΩ CC: R8 = 5.11 kΩ, R10 = 17.8 kΩ • For 400-mΩ CC: R8 = 6.49 kΩ, R10 = 16.5 kΩ • For 500-mΩ CC: R8 = 7.68 kΩ, R10 = 15.4 kΩ Refer to the TPS2549-Q1 datasheet (SLUSCE3) for more information. NOTE: The values shown for R8 and R10 take into account the effects of the TPS2549Q1 power switch and J1 receptacle/plug resistances (approximately 0.1 ohms, total). The effects of R5 are also included. Designs which do not need to account for these losses can exclude these from the equations. 2 TPS2549Q1EVM-729 Evaluation Module SLVUAK6A – October 2015 – Revised September 2016 Submit Documentation Feedback Copyright © 2015–2016, Texas Instruments Incorporated Schematic www.ti.com 3 Schematic Figure 1 illustrates the EVM schematic. 1 2 3 4 5 6 A A 1,2,5,6 HVS INPUT POWER 7V-18V, 1.5A VIN 12 13 VIN VIN CBOOT 3 11 EN SW SW 1 2 FB 9 BIAS 5 1uH R2 1.00M D1 (40V Transient) C1 10µF 15V D2 C2 10µF C3 0.1µF R3 C5 10µF J3 5VDC U1 L1 Q1 HVIN 100k 8 R7 0 DNP 39V 3.32 RESET 4 VCC 7 FPWM 6 SYNC VCC R6 100k 14 B C4 R4 0.47µF SW R23 5VP L3 2.2uH 0 R8 3.83k VFB R1 BIAS C10 0.022µF 0 AGND PGND PGND PAD NC 200mΩ CSPORT TP8 10 15 16 17 R5 49.9 C9 DNP220uF C12 2.2µF C6 22µF C7 22µF TP9 C8 22µF LOOP B LM53603AQPWPRQ1 C11 2.2µF R9 0 R10 19.1k FSW = 2.1MHz 200mΩ VFB 5VDC GND R11 5.62k R12 10.0k R14 10.0k 5016 D3 Red D4 Blue TP3 TP4 TP2 D- C D+ GND 5V @ 2.4A TP5 5VBI 1 5 VBUS J5 J2 J1 U2 2 DM_OUT 3 1 DP_OUT Sx 9 Fx 13 CS 4 EN 5 4 C17 10µF R16 6 CSPort TP6 0 R17 100k R18 R19 R20 100k 100k 100k 6 7 8 IN OUT STATUS ILIM_LO ILIM_HI FAULT DP_IN DM_IN CS EN DP_OUT DM_OUT CLT1 CLT2 CLT3 GND PAD 5VBO 12 15 16 10 11 3 2 ILIM_LO ILIM_HI C16 0.1µF 2 DM_IN 3 DP_IN DP_IN DM_IN R13 2.00k 4 DP_OUT DM_OUT C VBUS DD+ GND 14 17 R21 19.1k GND C18 10µF VBUS 1 6 5 J4 TP1 R22 80.6k C13 0.1µF C14 47µF C15 47µF D5 Green TP7 TPS2549Q1RTE J6 CTL1 CTL2 CTL3 1 3 5 7 GND 2 4 6 8 D D Texas Instruments and/or its licensors do not warrant the accuracy or c mpleteness of this specification or any information contained therein.

Connect the exposed pad to the GND pin and the system ground plane using an array of vias. • IN pin bypass capacitance: Place the 0.1-μF bypass capacitor near the IN pin and make the connection using a low inductance trace. • DP-OUT/DM-OUT, DP-IN/DM-IN traces: Route these traces as controlled impedance differential pairs per the USB-2.0 specification. Minimize the use of vias in the high speed data lines. Figure 7 provides a good signal routing example for the high-speed data traces. In this example, the data pairs are routed as edge-coupled microstrips with nominal differential impedance of 90 Ω. The reference plane is tied to GND and is shown in Figure 6. Ensure that the reference plane is void of cuts or splits above the differential pairs to prevent impedance discontinuities. • ILIM_LO and ILIM_HI Pin Connections: Current-limit, set-point accuracy can be compromised by stray current leakage from a higher voltage source to the ILIM_LO or ILIM_HI pins. Ensure that there is adequate spacing between IN pin copper/trace and ILIM_LO pin trace to prevent contaminant buildup during the PCB assembly process. 5.3 EMI Containment The following list describes EMI containment guidelines: • Use compact loops for dv/dt and di/dt circuit paths (power loops and gate drives). • Use minimal, yet thermally adequate, copper areas for heat sinking of components tied to switching nodes (minimize exposed radiating surface). • Use copper ground planes (possible stitching) and top layer copper floods (surround circuitry with ground floods). • Use 4-layer PCB, if economically feasible (for better grounding). • Minimize the amount of copper area associated with input traces (to minimize radiated pickup). • Maintain physical separation between input-related circuitry and power circuitry (use ferrite beads as boundary line). • Possible use of common-mode inductors 12 TPS2549Q1EVM-729 Evaluation Module SLVUAK6A – October 2015 – Revised September 2016 Submit Documentation Feedback Copyright © 2015–2016, Texas Instruments Incorporated Bill of Materials www.ti.com 6 Bill of Materials Table 4 lists the EVM BOM.
