Hello all,
I saw that the PMIC chooses power from external sources like DC and USB. It(PMIC) also choose from a lithium cell, and the choosen output is on net 5V_SYS. Since 5V_SYS must always be 5v, in case the PMIC chooses lithium cell as a power source then 5V_SYS will be equal to voltage of the cell? Then how will the system function if they expect 5V? I cannot see any BOOST circuit in PMIC other that WLED driver.
