2.1.2.3 JP4 (Internal or External VCC Selection)

The JP4 jumper is for the internal LDO or external VCC selection. By default, the jumper is set to the VCC position and the device selects an internal LDO as the VCC source.

To minimize the power dissipation of the internal LDO when both input voltage and output voltage are high, an external 5V power supply can be applied at the VCC pin to supply the TPSM852892. Place a jumper across EXTVCC and AGND to set the device VCC source externally. The external 5V power supply must have at least 100mA output current capability and must be within the 4.75V to 5.5V regulation range.
