SLVUCS0 july 2023 TPS552872 , TPS552872-Q1
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 TPS552872 and place a jumper across EXTVCC and GND .
