Power control device

摘要

A power control is disclosed, which relates to a technology for stably performing a power ramp-up operation during a power-up operation of an integrated circuit (IC) having heterogeneous power. The power control device includes: an amplifier configured to perform level shifting of a second power-supply voltage level to a first power-supply voltage level according to an input signal during an initial power-up operation section, and output the level-shifted output signal; an initialization unit configured to set an output signal level of the amplifier to the first power-supply voltage level according to a control signal during the initial power-up operation section, and output the first power-supply voltage level; and a latch unit configured to latch an output signal of the initialization unit according to the second power-supply voltage level during the initial power-up operation section.
