Before Using the Eval Board
Caution
• Follow the electrical connection instructions for the
evaluation board carefully. Reverse Connections on the
input or the output can cause permanent damage.
• Do not operate the input voltage higher than the specified
values. Overvoltage on the input to the device will cause
permanent damage.
• This product contains a printed circuit board utilizing surface
mounted devices. PCB stresses such as bending, twisting
etc. can cause damage. Please handle with care.

Getting Started with the i3A
Device Introduction
I3A Series DC/DC Power Modules
9-53V Input, 4.5 & 8A Output
100W 1/32nd Brick Power Module
I3A power modules perform local voltage conversion
from a 12V, 24V, or well regulated 48V bus. The i3A
series utilizes a low component count that results in
both a low cost structure and a high level of
performance. The open-frame, compact, design
features a low profile and weight that allow for extremely
flexible and robust manufacturing processes. The ultrahigh
efficiency allows for a high amount of usable power
even in demanding thermal environments.

Operation
•Once input voltage is applied, either of the converters can be
turned on or off using ON/OFF toggle switch.
•User can change output voltage by using Vo1 or Vo2 Trim
adjust potentiometer:
•V01 Adjustment Range: 3.3 – 16.5 Volts
•Vo2 Adjustment Range: 5 – 30 Volts
•Please note the specified operating ranges and keep in mind
that the positive output units are step down converters. The
input voltage to the converters must always be greater than the
output voltage. Please see charts below:

Setup Example Using Scope
• An oscilloscope can be connected to the inputs and the
outputs to observe converter behavior.
• Top trace shows input voltage rise to 48 VDC.
• Bottom Trace shows converter startup characteristic into
full load.

Appendix
Scope Measurement Technique
When making sensitive measurements a vertical mini-probe socket should be used to connect
the oscilloscope probe to minimize loop area of the measurement leads. See scope connection
below using Agilent P/N N2768A.
