TUSB9260 DEMO Board Block Diagram
Figure 1 represents the block diagram of the TUSB9260 DEMO Board. The board is designed to be
powered from either a 12-V DC wall-wart (not supplied) or via USB cable power.

12-V DC Jack
The DEMO Board can operate from a standard DC jack for connecting an external 12-V wall-wart. The
wall-wart should be rated for 12 V with at least a 2-A current rating. The tip of the DC jack has positive
polarity. A wall-wart is not supplied with this reference design demonstration module, leaving it capable of
bus power mode by default. In this mode, only Solid State Drives will work. If other higher current hard
drives are to be used a wall-wart will have to be used.

Cable Power vs. Self Power
The DEMO Board can be configured to operate off of cable power or use the 12-V wall-wart. To configure
the board to use cable power jumper J4 must have a jumper placed across pins 1 and 2. When configured
for cable power mode only 5-V and 3.3-V are available at the SATA connector. Therefore only SATA
devices such as SSD drives may operate in this mode.
For self power mode J4 must have a jumper placed across pins 2 and 3. In this mode any SATA device
can operate since 12 V, 5 V, and 3.3 V are available at the SATA connector.

Power Switch
The DEMO Baord uses a TI TPS2561 power switch. This switch serves two purposes. It limits the amount
of in-rush current on VBUS and it allows power to the SATA connector to be switched via the TUSB9260.
The switch is controlled via GPIO10 from the TUSB9260 and power faults can be monitored by GPIO11.
By default the DEMO Board is configured to always apply power to the SATA connector and power faults
are not monitored.

3.3-V, 1.8-V, and 1.1-V Regulator
The DEMO Board utilizes a TI TPS650061 regulator to power the TUSB9260 and associated circuitry.
1 Push Button Reset
Connected to the TPS650061 is a push button (SW2) that can be used to reset the TUSB9260 to its
default state. When pressed the global reset terminal (GRST#) on the TUSB9260 will be driven low.
