- Recently, most of electronic systems require that the power consumption is reduced and the reliability is enhanced.
Power management integrated circuits (PMICs) are a system block in a system-on-a-chip (SoC) device for managing power
consumption. PMICs are often used in liquid crystal display (LCD) applications using light-emitting diode (LED) backlight or
battery operated devices such as mobile phones and portable media players. PMICs include a DC-DC converter, an AC-DC
rectifier, a DC-AC invertor, and an AC-AC cycloconvertor. In mobile devices, the potable battery is used and DC-DC converters
are applied to generate required DC voltages. In many consumer electronics, a AC-DC rectifier is used to generate DC voltage
and the generated DC voltage is converted to required DC voltages by DC-DC converters. Many PMICs are often fabricated by
bipolar-CMOS-DMOS (BCD) process to sustain high voltage.
