Notable features of these LDO regulators include thermal and current- limit shutdown protection, a Power Good function, pin-selectable output voltage, low dropout, and wideband performance. The EVM contains a single linear regulator in a 5-mm x 5-mm, QFN (RGW), thermally enhanced, PowerPad™ package. This regulator, including external components, is capable of delivering up to 3 A (depending on the LDO regulator) to a dynamic load across the full recommended input and output voltage range of the LDO regulator. A multipin header with jumpers is provided to enable easy manual selection of the output voltage.

See the Assembly Layer diagram, Figure 4, for the location and orientation of referenced components. 2.1 Input/Output Connector-Headers and Jumper Descriptions • • • • • J1-VIN – Positive (+) input power supply voltage test and measurement header. J2 – VOUT – Output voltage test and measurement header. J3 (pin 1) – VOUT – Regulator output to a high-current load (up to 6 A). J3 (pin 2) – GND – Ground return from the load (up to 6 A) J4 (pin 1) – VIN – Positive (+) input power supply connector. NOTE: Twist the positive input lead and ground return lead from the input power supply, and keep them as short as possible to minimize EMI and source inductance. Additional bulk capacitance, 68 µF at C5, was added to the EVM to counter source inductances that may cause ringing on the load transient waveform during high-current transients. This bulk capacitance is unnecessary in a typical application circuit. • • J4 (pin 2) – GND – Negative (–) input power supply return connector. See preceding J4 –VIN (pin 1) note. J5 - Header for setting the output voltage. Output Voltage Set: The output voltage is set by jumpering J5 header pins, each assigned to a given voltage level, to ground where VOUT = Vref + (sum of jumper-voltages). J5 header pins are numbered sequentially, odd pins (1,3,5, …, 13) ascending leftward of pin 1 on the top row. All odd pins are connected to ground. Each even pin is numbered right to left sequentially (2,4,6,…,14) on the bottom row; and each even pin is assigned a unique voltage level. See the pin-to-pin output voltage assignments in the following table. VOUT = Vref + (Sum of Voltage Levels) Voltage Level Voltage Set Pins Ground Pins 50 mV 2 1 100 mV 4 3 200 mV 6 5 400 mV 8 7 800 mV 10 9 1.6 V 12 11 unused 14 13 • • • • • • • • 2 Example: Set VOUT to 1.8 V. Connect shorting jumper from pins 10 to 9, 8 to 7, and 4 to 3. VOUT = Vref + 800 mV + 400 mV + 100 mV = 1.8 V J6 – GND – Ground header for test and measurement of VIN. J7 – GND – Ground header for test and measurement of VOUT. JP1 – EN – Enable (Disable) header. Enable the LDO output by shorting EN (pin 2) to ON (pin 1). Disable the LDO output by shorting EN (pin 2 ) to OFF (pin 3). TP1 – Power Good (PG) test point. TP4 – VIN test point for most accurate measurement of the input voltage characteristics. TP2 – Ground test point to be used with TP4. TP5 – VOUT test point for most accurate measurement of the output voltage. TP3 – Ground test point to be used with TP5.

Program the desired output voltage per instruction 2.1, bullet J5. Use the shorting jumpers provided with the EVM to jumper the header pins. Note that the EVM is preset for VOUT equal to 1.8 V. The jumper across J5 pins 13 to 14 is no-connect and unused. Disable the EVM. Add a shorting jumper to JP1 from EN (pin 2) to OFF (pin3) Input Power Supply connection. Before connecting the input power supply to the EVM, verify that its output voltage is set to the desired supply voltage (less than 6.5 V) and that its current limit is set to approximately 4 A. Now turn off the power supply. Connect the positive voltage lead (+) from input power supply to VIN (J4, pin 1) of the EVM. Connect the ground lead (–) from the input power supply to GND (J4, pin 2). Note that for the recommended best thermal and ac performance, ensure that the input voltage at TP4 is 0.5 V to 1 V above VOUT. Connect a 0-A to 2-A load between VOUT (J3, pin 1) and GND (J3, pin 2). Turn on the input power supply. Verify that the output voltage, VOUT, is near 0 V. Enable the output by reconnecting the jumper on JP1 to short the EN (pin 2) to the ON (pin 1). Vary the load current and VIN voltage as necessary for test purposes. Note that power dissipation (Pdisp) across the TPS7A7X00 itself depends on the VIN-to-VOUT voltage drop and the output load current, ILoad (Pdisp = (VIN – VOUT)×ILoad). If the power dissipation is high, then the customer may see the output voltage transitioning on-off-on due to the shutdown effect of the thermal-limit shutdown circuit. Test Results This section provides typical performance waveforms for the TPS7A4001EVM-709 characteristic of this EVM design. 4.1 Turnon Characteristic Figure 1 shows the VOUT ramp-up waveform at turnon (ENable) as well as the input surge current into the IN pin of the LDO itself when the LDO starts up into a fully loaded output.

Use Equation 1 to approximate the worst-case junction temperature for the application: TJ = TA + Pd x θJA (1) where TJ is the junction temperature (°C), TA is the ambient temperature (°C), Pd is the power dissipation in the device (W), and θJA is the thermal resistance from junction to ambient (°C/W). The maximum silicon junction temperature must not be allowed to exceed 125°C for reliable operation. The layout design must use copper trace and plane areas smartly, as thermal sinks, so as to not allow TJ to exceed the absolute maximum rating under all load, voltage, and temperature conditions for a given application. The designer must carefully consider the thermal design of the printed-circuit board (PCB) for optimal performance over temperature. For this EVM, Figure 6 shows that the RGW package footprint employs a square thermal pad, centered under the device, for conducting heat to the copper-spreading layers of the PCB. The thermal pad is soldered directly to a pad on the PCB containing a 5x5 pattern of 10-mil vias for conducting heat to the bottom-side ground plane copper. Approximately 4 in2 of 2-oz copper is used on the bottom side of the EVM for dissipating heat generated by the LDO regulator. Table 1 is based on thermal resistance information from the Thermal Information Table of the TPS7A7x00 data sheet for comparison with the approximate thermal resistance, θJA, calculated for this EVM layout to show the variation in junction-ambient thermal resistances for varying copper areas. The High-K thermal resistance, θJA, is determined using a standard JEDEC High-K (2s2p) board having dimensions of 3-inch x 3-inch with two 1-oz internal power and ground planes and one 2-oz copper bottom plane for spreading/sinking heat from the IC component.

It should not be used as all or part of a finished end product. Your Sole Responsibility and Risk. You acknowledge, represent and agree that: 1. 2. 3. 4. You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees, affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes. You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates, contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard. You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even if the EVM should fail to perform as described or expected. You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials. Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in development environments should use these EVMs. Agreement to Defend, Indemnify and Hold Harmless.
