2.2 Power Supplies

By default, the TSWDC155EVM provides the ADS9212EVM with a 3.3V supply (3P3V). The ADS9212EVM has a TPS61070 boost converter that boosts the 3.3V supply to 5.4V. By default, this voltage is applied to low-dropout regulators (LDOs) to derive the AVDD_5V, VDD_1V8, and IOVDD supplies when JP4 is in the [1-2] position. U2 (TPS7A2050) provides the 5V AVDD supply and U3 and U6 (TPS7A2018) provide the 1.8V DVDD and IOVDD supplies, respectively. The LDO input voltage (TP1) can be changed to an external source (5.2V to 5.5V) applied to terminal block J1 by placing a shunt on JP4 in the [2-3] position. In this case U1 (LM66100), provides reverse polarity protection if the connection is wired incorrectly. The power tree schematic for the ADS9212EVM is shown in Figure 2-2.
