2.2.4 JP7 (EXTVCC)

EXTVCC pin input jumper. Place a jumper across EXTVCC and VCC to select internal LDO. To minimize the power dissipation of the internal LDO when both input voltage and output voltage are high, an external 5-V power source can be applied at the VCC pin (JP4) to supply the TPS55289 and place a jumper across EXTVCC and GND .
