3 UCD90120/4 EVM GUI Setup
3.1 UCD90120/4 EVM GUI Installation
The UCD90120 and UCD90124 EVMs use the Texas Instruments Fusion Digital Power Designergraphical user interface (GUI) which may be downloaded from the following web site:http://focus.ti.com/docs/toolsw/folders/print/fusion_digital_power_designer.html
Place the TI-Fusion-Digital-Power-Designer-zip file in a known location on the PC. Unzip theTI-Fusion-Digital-Power-Designer-zip file.
Double click the unzipped TI-Fusion-Digital-Power-Designer-exe file. Proceed through the installation byaccepting the installer prompts and the license agreement. Accept the GUI suggested default PCinstallation locations to complete the install.
Once the GUI completes the installation it will start. The first time the GUI is launched on a particular PCthe user may be prompted to select a device. Choose UCD9xxx. Afterwards, the GUI may be closed.
Note that the TI-Fusion-Digital-Power-Designer v1.6.105 was used for the examples to be shown later inthe document.

3.2 UCD90120/4 EVM GUI Operation
The EVM comes pre-loaded with a 12 rail default project that sequences the EVM rails on at power up. Itis a good idea to export the default project to a file on the PC prior to making changes.
3.2.1 Launch TI-Fusion-Digital-Power-Designer
Navigate to the location where the Fusion GUI is installed and (Start, All Programs, Texas InstrumentsFusion Digital Power Designer, Fusion Digital Power Designer) and start it. A window similar to thefollowing will appear.

5 Description
The following paragraphs describe the UCD90120/4 EVM functionality and operation.
5.1 Communication Interfaces
Several communication interfaces to the UCD90120/4 are provided on the EVM.
5.1.1 USB Interface
An onboard USB to PMBus interface is provided through the USB Input (J3) connector. D56 provides USBattach status. The presence of USB power at J3 activates buffer circuitry which gives control of the PMBusto the on board circuitry. The absence of USB power at J3 gives PMBus control through the ExpansionPMBus (J77) connector.
5.1.2 PMBus
Standard PMBus interface is provided to the UCD90120/4 through the J77 connector when the on EVMUSB-PMBus interface is not used. PMBus addressing is set using the J18 jumper block for ADDRSENS1and ADDRSENS0 respectively. ADDRx=8 and ADDRx=5 positions for each are provided. The EVMcomes with PMBus address set to 101 decimal.
PMBus Address (decimal) = 12 × ADDR1 + ADDR0 jumper block setting.
5.1.3 JTAG
Standard JTAG programming interface is provided to the UCD90120/4 through the J9 connector. InstallJ6, J7, J11, and J12 jumpers and ensure that rail 9-12 enable jumpers (J47, J53, J59, J65) are removedwhen using the JTAG interface.
5.2 Power
5.2.1 Input Power
The 12VDC EVM input power is provided through J1 (standard DC jack) or J2 (screw jack). A wall orlaptop adapter with 500mA (UCD90120EVM) or 2000mA (UCD90124EVM running a fan) capability and2.5mm I.D. x 5.5mm O.D. x 9.5mm DC jack can power the EVM. Reverse voltage protection and inrushlimiting is provided for 12VBUS. The 12VBUS signal is distributed for fan power and Local 3.3V supply.
5.2.2 5VBUS
5VBUS is derived from 12VBUS and provides the input voltage for rails 1-12. D5 will illuminate when5VBUS is present.
5.2.3 L3P3V
L3P3V is derived from 5VBUS and provides a general purpose 3.3V supply for the common onboardfunctions. The L3P3V jumper (J4) is installed to provide a connection to the 3P3V node.
5.2.4 V33D
The V33D node is connected to the UCD90120/4 digital and analog supply pins. V33D can be sourced by3P3V or Local V33D using the J5 jumper. D9 will illuminate when V33D is present.
5.2.5 Local 3.3V

5.5 Analog Monitor Inputs
The UCD90120/4 monitor inputs MON1-13 can be used to monitor onboard or off board voltages.Jumpers are used to select the analog source.
5.5.1 MON1 and MON4–MON11
MON1 and MON4-11 can be sourced by the onboard rail (L#) or an external (E#) voltage.
5.5.2 MON2, MON3, MON12 and MON13
MON2 can be sourced by the onboard rail (L2), an external (E2) or the on board temperature sensor (T1)voltage. MON3 can be sourced by the onboard rail (L3), an external (E3) or the on board current monitor(C1) voltage. MON12 can be sourced by onboard rail (12L), an external source (12E) or the onboard fantemperature potentiometer input (TEMP MON) voltage. MON13 can be sourced by the V33D or 12VBUSvoltage.
5.5.3 Monitor Scaling
For the external monitor jumper positions (E1-E4), the external supply can be scaled by a selectable factorof 2 for monitoring external voltages up to 5V or 6 for monitoring external voltages up to 15V. For MON13,the scale factor is 6 for the 12VB position and 2 for the V33D position. For all other MON jumper positions,the scale factor is 2.
5.5.4 Monitor Fault Injection
Under voltage or over voltage faults can be injected on MON 5–MON12 through the use of on boardswitches (S2, S4, S6, S8, S3, S5, S7, S9 respectively). The switches provide a fault bias on the nominalvoltage of approximately ±20%

5.10 Fan Interface
The UCD90124 provides support for up to four fans. The UCD90124EVM provides a single fan interfacefrom J66. The UCD90124EVM interface can support three fan types including 2-wire, 3-wire, and 4-wire.The FAN connector has four terminals (12V, GND, Tach, and PWM).
5.10.1 Fan Tach Input
The fan tach signal is an input to the UCD90124 providing an indication of fan speed based on signalfrequency. The EVM Tach input signal is conditioned prior to being connected to the UCD90124 and caninterface with either a 3.3V or 5V signal using J72. Install a shunt in the TACH position of J67 to connectthe conditioned signal to the UCD90124. The TACH signal at J66-2 is inverted by the conditioning circuitryprior to J67.
5.10.2 Fan PWM Output
The fan PWM signal is an output from the UCD90124 providing fan speed control using a pulse widthmodulated signal. The UCD90124 output signal can come from either PWM1 (J67 in the PWM position) orFPWM5 (J70 in the FPWM5 position). The PWM1 or FPWM5 output signal can directly drive the fan PWMinput (four wire fan with J68 in the 4W position) or be conditioned prior the fan PWM input (two or threewire fan with J68 in the 2/3W position). When J68 is in the 2/3W position, the PWM signal at J66-3 candrive or modulate the ground of a two or three wire fan. When J68 is in the 2/3W position, the PWM signalat J66-3 can provide a 3.3V, 5V, or 12V level PWM signal with appropriately installed shunts on J69 foruse with four wire fans. When J68 is in the 2/3W position, the PWM1 or FPWM5 signal at J70 is invertedby the conditioning circuitry prior to J66-3.
5.10.3 Fan Temperature Simulation
An onboard potentiometer (TEMP MON) can be used to simulate analog temperature when used inconjunction with the fan interface for fan speed control. The potentiometer voltage can be monitored atTP54 (TEMP MON) through MON12. Install a shunt in the 12E position of J61 and install J71 (EVR12).The potentiometer voltage can be varied from 0 to approximately 4.2V. This voltage is scaled by 2 beforebeing sampled at MON12.

www.ti.com Layout Guidelines, EVM Schematic, and Assembly Drawings
7 Layout Guidelines, EVM Schematic, and Assembly Drawings
7.1 Layout Guidelines
Thermal pad
The thermal pad provides a thermal and mechanical interface between the device and the printed circuitboard (PCB). While device power dissipation is not of primary concern, a more robust thermal interfacecan help the internal temperature sensor provide a better representation of PCB temperature. Connect theexposed thermal pad of the PCB to the device VSS pins and provide at least a 4 × 4 pattern of PCB viasto connect the thermal pad and VSS pins to the circuit ground on other PCB layers.
Supply voltage decoupling
Provide power supply pin bypass to the device as follows:
• 0.1µF, X7R ceramic in parallel with 0.01µF, X7R ceramic at pin 47 (BPCAP)• 0.1µF, X7R ceramic in parallel with 4.7µF, X5R ceramic at pin 44 (V33D)• 0.1µF, X7R ceramic at pin 7 (V33DIO)• 0.1µF, X7R ceramic in parallel with 4.7µF, X5R ceramic at pin 46 (V33A)
Digital output signals
Depending on use and application of the various GPIO signals used as digital outputs, some impedancecontrol may be desired to quiet fast signal edges. For example, when using the FPWM pins for fan controlor voltage margining the pin will be configured as a digital clock signal. Route these signals away fromsensitive analog signals. It is also good design practice to provide a series impedance of 20–33 Ω at thesignal source to slow fast digital edges.
PMBus clock and data
Route PMBUS_CLK and PMBUS_DATA in a careful fashion away from sensitive analog signals. Providea series impedance of 20–33 Ω at the signal source.
7.2 EVM Schematic
The searchable PDF of the schematic is appended to this User's Guide.
7.3 Assembly Drawings
The assembly drawings are appended to this User's Guide. The topside and bottomside componentlayouts are searchable.
