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.

Introduction
The purpose of the UCC25640EVM-020 (EVM) is to aid in evaluation of the UCC256403 and UCC256404
LLC resonant controller. The EVM is a stand-alone LLC resonant half-bridge DC-DC power converter
designed to operate with DC input from 365 VDC to 410 VDC, AC input from 85 to 265 VRMS, 47 to 63 Hz,
and a nominal output of 12 VDC up to 180-W. The EVM is delivered using a diode rectifier at the output.
The user has the option to evaluate this converter with a synchronous rectifier (SR) by populating the
UCC24624 and SR FETs. This user’s guide provides basic evaluation instruction from a viewpoint of
system operation of the stand-alone LLC resonant power converter.

www.ti.com
Test Procedure
Use the following steps for the test procedure:
1. Refer to Section 5.2 for basic setup. The required equipment for this measurement is listed in
Section 5.1.
2. Before making electrical connections, visually check the board to make sure there are no suspected
spots of damage.
3. Keep the DC voltage source output off. Connect the DC source to J1 (+) and J2 (-). The DC voltage
source should be isolated and meet the IEC 60950 requirement. Set the DC output voltage within the
range specified in Table 1, between 365 VDC and 410 VDC; set the DC source current limit to 1 A.
CAUTION
The board has no fuse installed and relies on the external voltage source
current limit to ensure circuit protection.
4. Keep the AC voltage source output off. Connect the source with AC_neutral to J8-1, AC_earth to J8-2,
and AC_line to J8-3. Isolate the AC voltage source and meet the IEC 60950 requirement. Set the AC
output voltage and frequency within the range specified in Table 1, between 85 and 265 VAC and 47
to 63 Hz. Set the AC source current limit to 200 mA.
5. Connect an electronic load set to either constant-current mode or constant-resistance mode. The load
range is from 0 to 15 A.
6. If the load does not have a current or a power display, TI recommends inserting a current meter
between the output voltage and the electronic load.
7. Connect a voltage meter to TP10 and TP3/TP4 to monitor the output voltage.
8. Turn on the AC source output.
9. Turn on the DC source output.
8.1
Equipment Shutdown
Shut down the equipment using the following steps:
1. Shut down the AC voltage source.
2. Shut down the DC voltage source.
3. Shut down the electronic load.
WARNING
High voltage may still be present on the resonant capacitors after
turning off the DC source.

PFC Boost Front End Standby Power
Overview
UCC256404 includes a high voltage startup feature. This feature enables the controller to be powered by
a wide AC input, eliminating the need for an external supply to power both the PFC and LLC. When AC
power is applied to UCC256404, a JFET initially charges the VCC capacitor to provide the energy needed
to start the PFC and LLC power system. Once running, power for the PFC and LLC controllers is derived
from a bias winding on the LLC transformer. Figure 7 illustrates the described startup sequence.
UCC256403 does not include the high voltage startup feature and requires an external power supply as
described in Section 5.3.

of burst mode. The output voltage immediately exits standby mode, increasing to 12 V, when the BMT is
exceeded. It then drops to the 9.75 V standby output voltage level when the load falls below the BMT.
This behavior is due to the circuit explained in Section 10.2.

10.2 Standby Mode Circuit for TV Applications
For some applications such as LED or OLED TV, the AC/DC power supply is placed into a standby power
mode to meet light load efficiency requirements. In this mode, the output voltage is reduced and the LLC
converter is configured to operate in burst mode to minimize input power. A central control circuit
communicates with the AC/DC power supply to enter or exit standby mode as needed. In order to mimic
this system level behavior, an external standby circuit was added to this design. This external standby
circuit adjusts both the burst mode threshold setting and output voltage set point depending on the
magnitude of the output current.
This is accomplished by sensing the voltage across a current sense resistor.

The resulting voltage is fed to a current sense amplifier with a 200V/V gain. The amplifier output is
compared to a set reference voltage to determine when to enter or exit standby mode. Hysteresis is
implemented on the comparator using R52 and R48.
Figure 30. External Standby Circuit Current Sense Gain and Comparator
The standby circuit adjusts the output voltage set point by changing the feedback resistor divider ratio
through Q6 and R56. When in standby mode, the gate of Q6 is held low. When out of standby mode, Q6
is turned on to put R56 in parallel to R23.

The burst mode threshold is controlled by the standby circuit using transistor Q5. When in standby mode,
the base of Q5 is pulled low, connecting the top of the LL/SS resistor divider to RVCC. When out of
standby mode, Q5 is turned off, changing the burst mode threshold to the minimum burst threshold (0.2V).
For applications where the output voltage set point is decreased when in standby mode, it is possible to
get in and out of burst mode by changing the output voltage regulation set point. This is because the
change in necessary peak to peak voltage on the VCR waveform to regulate at the higher output voltage
is greater than the programmed burst threshold. For these applications, the burst threshold adjustment
circuit on the primary may not be necessary.
Figure 32. Burst Mode Threshold Adjustment
Please note that this external standby circuit was added to evaluation module only to mimic system level
behavior. This circuit is not required in order to design with UCC25640x.

Limited 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
to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by
neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have
been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications
or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control
techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.
User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10)
business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected.
2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit
User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty
period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or
replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be
warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
