PCB layout guidelines
Keep all wiring as short as possible to minimize the effects of parasitic components.
Install CIN and COUT as close to IC as possible to obtain a stable power supply.
Wider VIN, VOUT, GND wires can reduce the effects of thermal impedances and parasitic components.
By separating the small-signal GND from the power GND, the effect of noises caused by the return
current can be reduced.

Replacement in accordance with these regulations shall be performed using the send-back method.
Customer shall promptly submit an application for replacement at the Distributor's contact point to the contact
point instructed by the Distributor. Packaging for equipment set-up and transport at the customer's location shall
not be included in service in accordance with this regulation. In addition, the shipping fees at the time of shipment
shall be borne by each shipping source, except when the customer and us agree beforehand with each other on a
written basis. We assume that you will ship the defective product in the same hardware configuration (including the

TCKE8xx Series Evaluation Board Instruction Manual
Unless otherwise specified, this evaluation board is not intended for use by general consumers, not the finished
final product. It is intended only for preliminary feasibility assessment in a laboratory/development environment by
technical and electronics experts familiar with the hazards and application risks associated with the handling of
electromechanical parts, systems and subsystems. It is not intended to be used in whole or in part of the final product.
The Buyer of this Evaluation Board acknowledges, expresses and considers to have agreed to the following at the
stage when the Evaluation Board is put into service:
1. The purchaser of the Evaluation Board has a unique knowledge of national regulatory requirements in relation to
the final product and in relation to the use of the Evaluation Board for evaluation, testing and other purposes
(and/or the use of the purchaser's affiliates, affiliates, contractors or designees).
2. The purchaser of the Evaluation Board is fully and exclusively responsible for ensuring that the safety of the final
product and compliance with all such laws and other applicable regulatory requirements are complied with and
that the purchaser of the Evaluation Board is fully and exclusively responsible for ensuring the safety of the
activities performed by its employees, affiliates, contractors or designees using the Evaluation Board. In addition,
it is the responsibility to ensure that any contact (electronic and/or mechanical) between the Evaluation Board
and the human body has been designed with adequate insulation and means to safely limit the potential leakage
currents in order to minimize the risk of electrical shock.
3. Since the assessment board is not a completed product, it may not usually meet all applicable regulatory and
safety compliance standards (e.g. UL, CSA, VDE, CE, RoHS, WEEE) that may be relevant for similar items. Buyer of
this evaluation board is responsible for determining and/or guaranteeing compliance with applicable standards
and related certificates. The purchaser of this evaluation board will take reasonable safeguards to ensure that the
use of the evaluation board does not result in property damage, injury or death even if the evaluation board does
not perform as described or expected.
4. We will endeavor to properly dispose of and recycle the electronic components and packaging materials of our
evaluation boards.
It is important that this evaluation board be operated according to the user guidelines within the recommended
specifications and environmentally friendliness presented by Toshiba Devices & Storage Corporation. Exceeding the
specified evaluation board ratings (including but not limited to input and output voltages, currents, power, and
environmental ranges) may cause property damage, personal injury, or death. Loads applied outside the specified
output range can result in unintended and/or unstable operation and/or permanent damage to the evaluation board
and/or peripheral electronics. Refer to the user guidelines before connecting the load to the evaluation board output.
During normal operation, the case temperature of some circuit components may exceed 60°C, even if 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. They can be identified using
the schematics given in the user guidelines. Note that when measuring probes are placed close to these instruments,
these instruments may become very hot when touched. As with all measuring instruments, only qualified personnel
familiar with electronic measurements and diagnostics normally found in development environments should use
these evaluation boards.
