	The OMAP3430 boast the most advanced and effective power management techniques in the market. The chip makes exhaustive use of TI's SmartReflex technologies which include a broad range of intelligent and adaptive hardware and software techniques that dynamically control voltage, frequency and power based on device activity, modes of operation and temperature. Additionally the OMAP3430 is supported by the TWL4030 power management/audio codec companion device which is designed specifically to maximize battery life and boost system performance in mobile phones that leverage the OMAP3430 applications processor. The highly integrated TWL4030 combines SmartReflex-compliant voltage regulators and converters, a high-fidelity audio/voice codec, class-AB/D audio amplifiers, high-speed USB 2.0 OTG transceiver, battery charger circuitry and much more into a single chip, significantly reducing board space and system cost while managing power consumption efficiently.
