TUSB2E221EVM TUSB2E221EVM Power Configuration Overview Figure 2-1 TUSB2E221EVM Power Configuration Overview

The TUSB2E221 requires two supply voltages during normal operation. The 3.3V and 1.8V supply can be provided directly from an external source on pin 1 of the J14 and J16 headers. The TUSB2E221EVM also includes two onboard LDOs which generate 3.3V and 1.8V from a 5V power supply. The 5V supply can be provided through the micro-AB USB connectors, or provided via a 5V wall power supply.
