EVALUATION KIT CONTENTS
ADP5070RE-EVALZ or ADP5071RE-EVALZ evaluation board
ADDITIONAL EQUIPMENT NEEDED
DC power supply
Multimeters for voltage and current measurements
Electronic or resistive loads
GENERAL DESCRIPTION
The ADP5070RE-E VA L Z and ADP5071RE-EVALZ evaluation
boards demonstrate the functionality of the ADP5070 and
ADP5071 TSSOP dc-to-dc converters, respectively.
Use either board to evaluate simple device measurements, such
as line regulation, load regulation, and efficiency. Device features
can be demonstrated, such as selectable operating frequency,
soft start, sequencing, and slew rate control. The ADP7142 and
ADP7182 LDO regulators are also available on the boards as an
option for enhanced low noise output.
For more details about the dc-to-dc converters, refer to the
ADP5070 and ADP5071 data sheets. For further information
on the LDO regulators, refer to the ADP7142 and ADP7182
data sheets.

EVALUATION BOARD HARDWARE
EVALUATION BOARD CONFIGURATIONS
The evaluation boards are configured to provide a ±15 V output
from a 3 V to 5.5 V input. The optional LDO regulators are
configured for a 12 V output (ADP7142) and a −12 V output
(ADP7182).
Table 2 and Table 3 list the components for the ADP5070 and
ADP5071 boards, respectively.
Table 4 lists the components common to both designs, including
the ADP7142 and ADP7182 LDO regulators.
The boards allow the end user to customize the design; refer to
the ADP5070 and ADP5071 data sheets or to the ADIsimPower
tools to obtain alternative component values. If the design is
customized, it is possible to obtain more than 70 V between the
positive and negative terminals on the boards. It is the responsi-
bility of the end user to ensure the boards are suitable for such a
design and to take appropriate safety precautions.
Figure 2 outlines the board features available to the user.
Figure 3 and Figure 4 highlight the ADP5070/ADP5071 and
supporting components, including locations for optional com-
ponents if the user wants to modify the design.
