TPS25741EVM-802 and TPS25741AEVM-802 Evaluation
Module User Guide for Desktops
This user’s guide describes the TPS25741 and TPS25741A evaluation module (TPS25741EVM-802 and
TPS25741AEVM-802). The TPS25741EVM-802 and TPS25741AEVM-802 contain evaluation and
reference circuitry for the TPS25741 and TPS25741A, which are dedicated USB Type-C™ power delivery
(PD) source controllers. The TPS25741 and TPS25741A devices support multiplexing of two existing input
voltage rails onto VBUS. This feature is uniquely suitable for desktop applications where 5 V and 12 V (or
5 V and 9 V) already exist. These EVMs are designed to highlight the mux feature, by using 2 Buck
converters to create 5 V and 12 V (or 5 V and 9 V) and then multiplex between them. The EVMs are also
designed to support port power management (PPM) for dual-port applications, by connecting two EVMs
together. In addition, this EVM supports BC1.2 charging using the TPS2514A connected to the DP and
DM line.
This EVM features a barrel jack input with reverse voltage protection to allow for easy demonstration using
a 24-V, 60-W output adapter.

TPS25741EVM-802 and TPS25741AEVM-802 Evaluation Module User
Guide for Desktops
1 Introduction
The TPS25741EVM-802 and TPS25741AEVM-802 allow performance evaluation of the TPS25741 and
TPS25741A devices in a desktop-like application. Note that the two Buck converters are only used to
generate stable 5 V and 12 V/20 V (or 5 V and 9 V/15 V) power rails, in the same manner as desktops.
The TPS25741 and TPS25741A devices can be powered from the input of the DC/DC converter and do
not require an external LDO. The 5-V converter will not turn ON unless an upstream facing port (UFP) is
inserted. The 12-V converter is always on but will not be multiplexed onto VBUS until 12-V contract is
made.

2 Description
Referring to the schematics in Figure 3 and Figure 4, a 24-V DC input is applied at the J11 terminals or J9
and J13 connectors. There are two DC_DC output nodes, which are regulated by two separate TPS54531
(U1, U4) and associated circuitry.
A USB Type-C UFP is plugged in at J12. When the TPS25741 or TPS25741A detects the UFP via CC1 or
CC2, then Q7 will be turned on by GDNG. If a 5-V contract is established, Q8 will be turned on by G5V, so
5 V will be applied onto the VBUS. If a 12-V contract is established, Q8 is turned off first and then Q3 and
Q4 are turned on by GDPG, so 12 V will be applied onto the VBUS. The voltage request is processed by
the TPS25741 or TPS25741A and then is relayed by gate drivers (GDNG, G5V, GDPG). The relationship
between the VBUS and gate drivers is shown in Figure 2.
Figure 2. Switching Between 5 V and 12 V Using GDNG, G5V, and GDPG
The DC-DC converter can also implement a power saving feature when in unattached status. U4 is not
enabled until a valid UFP is inserted. By using the enable pin of TPS54531, power consumption can be
minimized. To configure U4 as always on, remove R45 and R51 and install R21.
For more information and detailed design information, refer to the TPS25741 and TPS25741A data sheet
(SLVSDJ5).

NOTE: DCDC_2 voltage is changed dynamically from V2 to V3 (or V3 to V2)
by CTL1. For V1 to V3 (or V3 to V1) transitions, a momentary pause
at V2 may be observed in the VBUS waveform. To inhibit the
momentary pause at V2, the CTL1 signal may be connected to GND
to default DCDC_2 at the V3 voltage instead of the V2 voltage. For
this configuration, use a jumper wire from TP5 to TP1, TP3, or TP10.

4.3 Equipment Setup
The following is required to set up the equipment:
• Power supply capable of 24 V and preferably 3 A (72 W)
• Resistive or electronic load
• PD-capable UFP to negotiate voltages.
• USB Type-C cable
5 Operation
Use the following steps to operate the EVM:
• Turn on the input power supply to 24 V.
• Connect the UFP to the TPS25741 or TPS25741A EVM through a USB Type-C cable.
• Make desired voltage requests from the UFP to TPS25741 or TPS25741A EVM.
• Connect load between J8 and J14 as desired to test features and other performance.
6 Test Results
This section provides typical performance waveforms for the TPS25741EVM-802 and TPS25741AEVM-
802 with VIN = 24 V at different load conditions. Actual performance data is affected by measurement
techniques and environmental variables; therefore, these curves are presented for reference and may
differ from actual results obtained.

STANDARD TERMS FOR EVALUATION MODULES
1. Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, and/or
documentation which may be provided together or separately (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance
with the terms set forth herein. User's acceptance of the EVM is expressly subject to the following terms.
1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility
evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not
finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For
clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions
set forth herein but rather shall be subject to the applicable terms that accompany such Software
1.2 EVMs are not intended for consumer or household use. EVMs may not be sold, sublicensed, leased, rented, loaned, assigned,
or otherwise distributed for commercial purposes by Users, in whole or in part, or used in any finished product or production
system.
2Limited Warranty and Related Remedies/Disclaimers:
2.1 These terms do not apply to Software. The warranty, if any, for Software is covered in the applicable Software License
Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM

Concerning EVMs Including Detachable Antennas:
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser)
gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type
and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for
successful communication. This radio transmitter has been approved by Industry Canada to operate with the antenna types
listed in the user guide with the maximum permissible gain and required antenna impedance for each antenna type indicated.
Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited
for use with this device.
Concernant les EVMs avec antennes détachables
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et
d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope
rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. Le
présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés dans le
manuel d’usage et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne
