General Texas Instruments High Voltage Evaluation (TI HV EMV) User Safety Guidelines
WARNING
Always follow TI's set-up and application instructions, including use of all interface components within their
recommended electrical rated voltage and power limits. Always use electrical safety precautions to help
ensure your personal safety and those working around you. Contact TI's Product Information Center
http://ti.com/customer support for further information.
Save all warnings and instructions for future reference.
WARNING
Failure to follow warnings and instructions may result in personal injury,
property damage or death due to electrical shock and burn hazards.
The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed
printed circuit board assembly. It is intended strictly for use in development laboratory environments,
solely for qualified professional users having training, expertise and knowledge of electrical safety risks in
development and application of high voltage electrical circuits. Any other use and/or application are strictly
prohibited by Texas Instruments. If you are not suitable qualified, you should immediately stop from further
use of the HV EVM.
1. Work Area Safety:
a. Keep work area clean and orderly.
b. Qualified observer(s) must be present anytime circuits are energized.
c. Effective barriers and signage must be present in the area where the TI HV EVM and its interface
electronics are energized, indicating operation of accessible high voltages may be present, for the
purpose of protecting inadvertent access.
d. All interface circuits, power supplies, evaluation modules, instruments, meters, scopes, and other
related apparatus used in a development environment exceeding 50Vrms/75VDC must be
electrically located within a protected Emergency Power Off EPO protected power strip.
e. Use stable and non-conductive work surface.
f. Use adequately insulated clamps and wires to attach measurement probes and instruments. No
freehand testing whenever possible.
2. Electrical Safety:
As a precautionary measure, it is always good engineering practice to assume that the entire EVM
may have fully accessible and active high voltages.
a. De-energize the TI HV EVM and all its inputs, outputs and electrical loads before performing any
electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely
de-energized.
b. With the EVM confirmed de-energized, proceed with required electrical circuit configurations,
wiring, measurement equipment hook-ups and other application needs, while still assuming the
EVM circuit and measuring instruments are electrically live.
c. Once EVM readiness is complete, energize the EVM as intended.

WARNING
While the EVM is energized, never touch the EVM or its electrical
circuits, as they could be at high voltages capable of causing
electrical shock hazard.
3. Personal Safety
a. Wear personal protective equipment e.g. latex gloves or safety glasses with side shields or protect
EVM in an adequate lucent plastic box with interlocks from accidental touch.
Limitation for safe use:
EVMs are not to be used as all or part of a production unit.

Label
Description
VIN, GND
J1 connects the input power to the TPS92682EVM-069 board. The board silkscreen
identifies VIN pins with "+" and the GND pins with "–" markings.
VOUT1, VOUT2 and GND
J2 is connected to the channel-1 output and J6 is connected to the channel-2 output of
the TPS92682-Q1 device. By default the board is configured as 2-phase . Therefore,
VOUT1 and VOUT2 are shorted together with a zero-Ω resistor, R8.
J8
VDD jumper
J8 is a jumper provided to share VDD with other SPI controlled EVM, in case a digital
supply is needed. For the operation of this EVM, leave this jumper open.
J3
PWM1 jumper
J4
PWM2 jumper
J9
SSN configuration jumper
J1
J2
J6
J3 and J4 are jumpers to allow for PWM signals to be applied to the two channels.
When the jumpers are removed and the R21 and R22 zero-Ω resistors are installed,
the PWM signals can be generated from the MSP-EXP432E401Y controller board.
When the jumpers are populated (by default), the PWM1 and PWM2 pins of the
TPS92682-Q1 are connected to VDD. The PWM signals can be used to disable the
associated channels in CV mode.
J9 allows configuration of the SSN chip select line, when multiple chips on the same
SPI bus are used. By default, evaluation module is configured to be connected to the
SSN0 of the MSP-EXP432E401Y controller board.

Because TPS92682EVM-069 is configured as a 2-phase CV boost converter, ensure the settings shown
in red in Figure 45 are correctly set to turn-on and regulate the output voltage.
The settings shown in Figure 43 are sent to the TPS92682-Q1 when the GUI is started. However, if the
power to the TPS92682EVM-069 is off when the GUI is started, the settings are not applied after the
power-on of the EVM. To make sure that all the required settings are applied, uncheck and re-check the
check-boxes in the GUI control box shown in Figure 43 and Figure 45.

Set the configuration to 2-phase by setting the Dual Phase check box
By default, the Clock Div is set to “2”, which corresponds with switching frequency of FSW=200kHz.
Set the channel-1 soft-start time to “100”. Two-phase mode does not require a soft-start time setting for
channel-2. Channel-1 soft-start time is used for both channels in 2-phase mode
5. In 2-phase mode, the output voltage VOUT is set by channel-1 V/I Adjust DAC. Set the DAC to 211 or
212 for VOUT ≈ 50 V. The feedback resistors are set on the TPS92682EVM-069, such that the
maximum setting of V/IADJ-DAC corresponds to VOUT ≈ 60 V.
