All three actions result in the Dialog PMIC powering down the voltage regulators in reverse order of the power
up sequence, except for VLDO1. Subsequently, pressing the POWER button will initiate the same power up
sequence as shown in
Table 5-1 .
The various power rails supplied by the PMIC are discussed in the SMD Power Rails subsection. Other features
of the Dialog PMIC implemented by the MCIMX53SMD board are discussed in the Backlight LED Driver , Touch-
Screen Operation , and Miscellaneous sub-sections.
5.2.1. SMD Power Rails
Table 5-2 shows all the voltage supply rails used on the MCIMX53SMD board, their voltages and the major
subsystems they supply on the board.
