DEMO MANUAL DC2086A
Description
Powered Programming
Adapter for Digital Power System
Management (PSM) Products
Demonstration circuit 2086A is an accessory board to
the DC1613A, DC2026A and DC590B that allows for a
higher current 3.4V or 5V output rail and the ability to
adapt different input cables to output cables. Extra power
is supplied to the downstream device from the DC2086A
when it is plugged into an external supply. This can be
done via any one of the three input methods: (a) 2.1mm
DC input jack, (b) 2-positon screw-terminal block, and
(c) USB 3.0 Micro-B connector. The DC590B and DC2026A
USB dongles both use a 14-pin ribbon cable for power and
communication to a connected system board, whereas the
DC1613A USB dongle uses a 12-pin ribbon cable for the
same purpose. The DC2086A can take either of these 12pin or 14-pin ribbon cable inputs and adapt to the 12-pin,
14-pin, or newer and smaller 4-pin or 3-pin connectors.
This means you are able to use the same USB dongle to
power and talk to any of your demo boards even when it
does not have the mating connector for the dongle. The
DC2086A also allows your PSM devices on your hardware
to be powered via the dongle as well as the ability to keep
the "brains" of the PSM device alive independent of the
power supply rails on the board, which is extremely useful
in any debugging situation.
The 2.1mm DC input jack and 2-position screw-terminal
block are in parallel and can accept any DC input between 4.5V and 18V. The USB 3.0 Micro-B connector is
backwards-compatible with any USB Micro-B connector, exactly like those found on modern cell phones and
consumer electronics. This simplifies cable requirements
when you can reach into your bag and pull out one cable
that powers all your devices, and plug this board in as if
it were your cell phone.

DC2086A Features
The DC2086A features two input ports supporting both
the current recommended 12-pin header used to connect
to the DC1613A as well as the legacy 14-pin header used
to connect to the DC590B. On the output side, there are
the same 12-pin and 14-pin headers in addition to a new
smaller footprint 4-pin header. This new header contains
ground, I2C Clock (SCL), I2C Data (SDA) and 3.4V power.
These four signals allow the minimum for communication
with LTpowerPlay™ and external bus controllers (SDA,
SCL and GND via 4-pin/3-pin output cable).

NOTES:
1. Total input current is limited to 2.5A.
2. When drawing current from both the 5V 3.4V rails simultaneously, the total combined output power is limited to 7W.
3. 4.5V is the minimum input voltage, but up to 4.75V input may be required for start-up. After the DC2086A is operational, only then is it possible to
regulate down to 4.5VIN.

DEMO MANUAL DC2086A
Simplified Block Diagram
The Simplified Block Diagram shows that the DC2086A
can power its output power rail from any combination
of three dedicated power input ports (wall power from
a 2.1mm barrel jack, turret power from screw terminals,
and via a USB connection) or the 5V rail on the upstream
12-pin or 14-pin ribbon cable. Priority for the ideal ORing circuits is given to the three dedicated power inputs
throughout the chain, making the assumption that if you
have it connected to an external power source it is the
highest current supply available in the system.
4
All three dedicated power inputs are fed into the internal
DC2086A VBUS. This is a LTC3575 flyback controller providing true magnetic isolation through a Würth 750311675
transformer. This protects your power supplies upstream
from anything catastrophic that the boards downstream
may experience.
The smaller 4-pin output connector does not have a 5V rail
available whereas the 12-pin and 14-pin cables do. Also
note that all signal lines are routed straight through from
the input connectors to the output connectors.

DEMO MANUAL DC2086A
When Do I Need This Board?
The DC2086A has many useful features that make it an essential accessory adapter to one of Linear Technology’s USB
dongles, such as the DC1613A, DC590B, and DC2026A.
The DC590B and DC2026A use a 14-pin ribbon cable
for power and communication to a system board,
whereas the DC1613A uses a 12-pin ribbon cable. The
DC2086A is more versatile and can accept either of these
12-pin or 14-pin ribbon cable inputs and adapt to the
12-pin, 14-pin, or newer and smaller 4-pin or 3-pin connectors.
If designing a board, we highly recommend putting one
of these connectors on your board. The reasons are: the
ability to program PSM devices onboard, powered via
the dongle, and the ability to keep the "brains" of the PSM
device alive independent of the power supply rails on the
board—which is useful in any debugging situation. When
used with LTpowerPlay software, the DC2086A provides a
powerful way to debug an entire power system. Failures are
quickly diagnosed using telemetry, fault status registers,
and the fault logs. The final system configuration can be
quickly developed and stored to the PSM products’ respective nonvolatile memories all using this one interface.
In addition to adapting to the various connectors, the
DC2086A has two higher current power rails which can
provide 3.4V and 5V power to the board. The current USB
dongle solutions, such as the DC1613A, can only source
around 100mA. This is generally sufficient to power a
single device and supporting hardware, and in some cases
approximately four LTC products. With the complexity
in today’s power systems, it is common to have more
devices that need power beyond the capability of the USB
dongles. In these situations, use the DC2086A to power
the board. The DC2086A provides up to 2.3A on the 3.4V
rail, which is more than enough to power over a hundred
devices on the same power source. Consult the data sheet
of the PSM device to verify (this generalization assumes
20mA per PSM device).

When Do I Need This Board?
Please see Figure 7, Figure 8 and Figure 9 for examples of
how to design your board to make full use of these strikingly important features and allow for your PSM products
to be powered from the DC2086A.
Choosing a connector with power means a minimum of
four pins, but it is recommended for all designs. It allows
for the most flexibility at all times and enables you to make
use of all of the features of the PSM device.
If you are unsure of which connector to choose to put
on your board, you can consult Table 1 through Table 4.
If needed, an adapter to the 4-pin output of DC2086A can
be made. Refer to Table 5.

The DC2086A uses a USB 3.0 SuperSpeed Micro-B male
connector as a possible input power source. This connector
is 100% backwards-compatible with the now ubiquitous
USB 2.0 Micro-B male connector that is found on the end
of countless device chargers and is officially the global
standard for charging with the title of Universal Charging
Solution.
If a legacy USB 2.0 Micro-B male connector is used with
the DC2086A, it will fit into the portion of the USB 3.0
Micro-B socket on the left of the device, as shown in
Figure 10.
To get the most output power from your DC2086A whilst
being supplied by the USB port, connect it to an external
wall charger with at least a 2A output rating. Newer smartphone and tablet chargers generally meet this specification,
as shown in Figure 12. The use of a lower output capacity
charger will only limit the total output power available from
the DC2086A.
If the DC2086A is powered from a computer port that does
not accept the charging port protocol, but does strictly
enforce downstream port power management, the total
input current will be limited to 100mA.
If the DC2086A is powered from a computer port that
does recognize the charging port protocol, the total input
current will be limited to 2.3A.
If the DC2086A is powered from a computer port with no
management, or a wall adapter with no management, it
will happily draw up to 2.5A through the USB connector. If
unsure whether the computer or wall adapter is managed,
do not use that port to power the DC2086A.
