Preliminary Technical Data
ADM106X EVAL BOARD HARDWARE
The ADM106x Evaluation Board is designed to provide all of
the necessary stimuli to the ADM106x, showing the many
features of the device in a compact, self contained environment.
The following pages contain a simple block diagram of the
functions on the board, followed by a detailed schematic of the
board and finally, the tracking, power and silkscreen layers for
board.
The two main features of the board are the programmable
voltage circuits and the output indicator LED’s. There are eight
programmable voltage circuits provided. The circuits are
labeled VX1, VX2, VX3, VX4, VP1, VP2, VP3, VP4. These
are programmable, via the Eval Board software, over a voltage
range of 0.6V to 6V. Programming of these supplies is detailed
in the software section of this Eval Note. The eight circuits
provide voltages to eight of the ten inputs to the ADM106x.
The inputs which do not have a programmable supply are VX5
(where a test point is available for the user for their own
external input) and VH, which has 12V driving it directly (or
alternatively, uses the programmable supply of VP4, if
required).
The ten output indicator LED’s are labeled PDO1 to PDO10.
These indicate a logic high on the output pins of the ADM106x.
The LED’s for PDO1- 6 are dual colour LED’s. This is to
indicate when a PDO is being used as a logic output or as a
FET driver output. Green indicates a logic output while red
indicates a FET driver output.
EVAL BOARD MANUAL SWITCHES
The ADM106x Eval Board uses only two manual switches. All
other switching functions are electronic and controlled using
the ADM106x software tool. Control of all of the board
functions is discussed in the software section.
The two manual switches are S1 and SW2. Details on these is
provided below.
S1 allows the user to connect a supply to the drain of one of the
six FET’s provided on the board. This allows the user to verify
the function of controlling a supply by having an N- Channel
FET placed in the supply path and controlling its turn on with
one of the FET drivers of the ADM106x. The default
connection of the switch is closed, thus connecting it to a 5V
supply on the board. When off, a supply can be connected by
the user to one of the test points provided. It is not
recommended that a supply greater than 5V be connected to
these test points (since with a gate voltage of 12V max., it may
be difficult to fully enhance the gate of a FET with V
Table 3 opposite indicates the function of this switch.

The second switch, SW2, is for setting the SMBus address of
the ADM106x. The format of the SMBus address for each of
the devices is XXXXX A1 A0. A1 and A0 are pins on the
device, allowing up to four ADM106x’s to be connected to the
same SMBus. The manual switch on the Eval board allows any
one of these four addresses to be set. The table below shows
the effect of settings these switches
