Abstract:
A method of operating a memory sub-system includes receiving an input voltage at a power management (PM) component of a memory sub-system, where the PM component includes a capacitive voltage divider (CVD), a linear voltage regulator (LVR), and a switching voltage regulator (SVR). The method includes determining whether the input voltage corresponds to a low power mode of the memory sub-system and that the input voltage is higher than an uppermost supply voltage at which a memory component of the memory sub-system is configured to operate. The method further includes selectably coupling, responsive to a determination of the low power mode, the CVD and the LVR and sequentially reducing the input voltage by the CVD and the LVR to a supply voltage for the memory component, where the supply voltage is not higher than the uppermost supply voltage at which the memory component is configured to operate.
