1. A power management apparatus, comprising:
an artificial intelligence (AI) controller configured to monitor a user pattern, based on frequency band selection information of all users using a base station, to predict the user pattern; and
a DC-DC converter configured to output a supply voltage based on the predicted user pattern,
wherein the AI controller is further configured to detect a load of a low-dropout (LDO) to control a core size, a soft-start time, a discontinuous Pulse-width modulation/digital power system management (DPWM/DPSM) mode, a gate driver size, and a switching frequency to track a minimum supply voltage satisfying a predetermined minimum noise performance based on an AI algorithm.
