least-significant bits of the 7-bit I2C address. See Table 2-1 for more information.
- J15 (ADR0):
Configures bit 0 of the device address
- J16 (ADR1):
Configures bit 1 of the device address
- J17 (ADR2):
Configures bit 2 of the device address
- Enable: This jumper
enables or disables the TPS7B780x-Q1.
- J5 (EN):
Enables the device by connecting EN to VIN or disables the device by
connecting EN to GND
