These highly integrated, flexible power management units are ideal for use in portable, battery-powered devices. They include a battery charger, DC-DC converters, LDOs and backlight drivers. They feature sophisticated power-saving functions such as dynamic voltage scaling and power-save modes to help extend battery run-time. Some of the devices also include audio functions such as a high-quality DAC and ADC, amplifiers, equalizers and an audio mixer.
