DC2086A

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 also allows users PSM devices on their 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.

• I2C/SMBus serial interface
• 2.3A at 3.4V and 1.3A at 5V output power
• 3.4V and 5V independent output power rails
• Cable adapter b/w 12/14-pin ribbon cables to 12/14-pin ribbon cables and 3/4-pin cables
• Supply input voltage range from 4.5V to 18V (J100: 2.1mm barrel jack)
• Supply input current of 2.5A (J100: 2.1mm barrel jack)
