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 be-tween 4.5V and 18V. The USB 3.0 Micro-B connector is backwards-compatible with any USB Micro-B connec-tor, 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.

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 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. 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

Dc2086A FeAturesThe 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).

DEMO MANUAL DC2086A
simpliFieD Block DiAgrAmThe 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 OR-ing 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.
All three dedicated power inputs are fed into the internal DC2086A VBUS. This is a LTC3575 flyback controller pro-viding 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 es-sential 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 con-nectors.
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’ re-spective 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).

DEMO MANUAL DC2086A
Please see Figure 7, Figure 8 and Figure 9 for examples of how to design your board to make full use of these strik-ingly important features and allow for your PSM products to be powered from the DC2086A.
If you are unsure of which connector to choose to put on your board, you can consult Table 1 through Table 4.
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 needed, an adapter to the 4-pin output of DC2086A can be made. Refer to Table 5.

usB connectors
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 smart-phone 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.
