Table of Contents www.ti.com User’s Guide TPS541620 2-Phase SWIFT™ Step-Down Converter Evaluation Module User's Guide ABSTRACT The TPS541620SEVM-050 evaluation module (EVM) features the TPS541620, a highly integrated non-isolated Dual DC-DC converter that is capable of high frequency operation in a 3 mm x 5 mm package. The device can be configured as two single 6-A rails or combined to drive a single 12-A current load. Though the TPS541620 is highly configurable, the TPS541620SEVM-050 is configured for 2-phase operation only. The Vout is configured for 1.0 V and can deliver up to 12 A of load current. Input and output capacitors are included on the board. Monitoring test points are provided on the board as well. Table 1-1. Device Information Ordering Code Configuration Input Voltage Output Voltage Output Current TPS541620SEVM-050 Single output fSW = 1 MHz VIN = 9 V to 15 V VOUT1 = 1 V: up to 12 A; 0 to 12 A Note The EVM has jumpers and test points that allow easy evaluation of steady state measurements such as efficiency, line/load regulation, input/output voltage ripple. Other tests such as frequency response, load transient, start-up, and power down can be performed.

The TPS541620SEVM uses a nominal 12-V bus to produce a regulated 1-V up to 12 A of load current. The TPS541620SEVM-050 only demonstrates the 2-Phase configuration. 1.1 Before You Begin The following warnings and cautions are noted for the safety of anyone using or working close to the TPS541620SEVM. Observe all safety precautions. Warning The TPS541620SEVM-050 engineering verification board may become hot during operation due to power dissipation. Avoid contact with the board. Follow all applicable safety procedures applicable to your laboratory. Caution Do not leave the EVM powered when unattended. ! WARNING The circuit board has signal traces, components, and component leads on the bottom of the board. This may result in exposed voltages, hot surfaces or sharp edges. Do not reach under the board during operation. WARNING The circuit board surface area may be hot under some operating conditions. To avoid injury, use caution when touching the board during operation. 1.2 Typical Applications • • • • • Wired and Wireless Infrastructure Equipment Ethernet Switches Router Network ASIC, SoC, FPGA, DSP I/O Voltage Rails Industrial Test and Measurement Equipment 1.3 Features • • 2 Regulated 1-V output for TPS541620SEVM up to 12-A output current Convenient test points for probing TPS541620 2-Phase SWIFT™ Step-Down Converter Evaluation Module SNVU686A – NOVEMBER 2020 – REVISED MAY 2021 User's Guide Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated www.ti.com Electrical Performance Specifications 2 Electrical Performance Specifications Table 2-1 lists the electrical performance specification (TPS541620SEVM-050) under room temperature 25°C.

The EVM is provided with input/output connectors and test points as shown inTable 4-1. A power supply capable of supplying 4 A or greater must be connected to J1 and/or J3 through a pair of wires 20AWG or lower. The Vout load must be connected to J2 and/or J4 through a pair of wires 20 AWG or lower. The maximum load current capability output is 12 A. Wire lengths should be minimized to reduce losses in the wires. The VIN input voltage can be monitored using TP3 with TP5 as the ground reference or using TP4 with TP6 as the ground reference. TP1 is used to monitor the output voltage VOUT with TP24 as the ground reference. Make sure jumpers J9 and J10 are set in the ON position which enables both the DC/DC converters on the TPS541620. Jumper J9 enables DC/DC1 of the TPS541620. Setting the jumpers to the OFF position will disable the DC/DC converter. Apply the input voltage supply of 12 V to J1 and/or J3. Connect your oscilloscope or multimeter probes to the appropriate test points to observe. Figure 3-1.
