3. How to set up
This chapter describes how to set up and connect jumpers. Please refer to the data sheet and
application notes of this product for the test conditions.
INPUT (VIN)
VIN terminal is connected to the positive of the power supply. Connect the positive terminal to VIN.
(Connect Ground (grounding) of the power supply side to the lower GND of VIN terminal.
OUTPUT (VOUT)
VOUT terminal is EVB output terminal. Connect the positive terminal of the load to VOUT terminal
(connect Ground (grounding) on the load side to the lower GND terminal of VOUT terminal).
OUTPUT (VOUT B)
VOUT B terminal is used when a MOSFET for reverse-current protection (RCB) is used. The gate-
voltage to drive MOS is supplied from EFET terminal described below.
VIN sense, GND sense, and VOUT sense and GND sense
These four terminals are used to accurately measure VIN or VOUT voltage by correcting the drop
voltage caused by the parasitic resistor of EVB. For example,when measuringthe on-resistance between
VIN-VOUT terminals, measure the potential difference between VIN sense-VOUT sense terminals to
calculate Ron unaffected by the parasitic resistance
EN/UVLO
EN/UVLO pin selects EN (enable) and UVLO functions. During normal operation, the center and left
(EN) terminals are connected for use. To use UVLO function, connect the center and the right (UVLO)
terminal.
EFET EFET is a terminal to be connected when RCB function is used. The right terminal of EFET symbol is
connected to EFET of the device. The left terminal of EFET notation (silk characters) is connected to
MOSFET gating terminal (in the default status, OPEN status because MOSFET is not installed). By
mounting MOSFET (mounting it later), it is possible to check RCB(Reverse Current Block) function.
dV/dT dV/dT pin is used to adjust the rise time.
The rise-time is adjusted by the capacitance between dV/dT terminal and GNDpin. Normally, 1nF and
max. 100nF are available.
ILIM ILIM terminal is used to adjust the overcurrent limit.
Adjust the overcurrent limit using a resistor (RILIM) between ILIM and GND terminals.
RILIM can range from 20kΩ to 300kΩ.

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.

Warnings, Limitations, and Disclaimer for Evaluation Boards
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.
