Today's smart phones and tablets combine incredible processing power (quad core gigahertz processors), memory, innovative software, and ubiquitous communications to provide both information and entertainment in a mobile environment.

Tablets utilize much of the same semiconductor technology as smartphones with the primary distinguishing feature being a larger screen. Tablets generally have a larger battery capacity and typically feature the most powerful processors available.


Power Management

Smartphones and tablets continue to expand their feature sets. Newer models employ higher performance processors, more memory, and additional features. The battery, however, must not increase in size, so power management ICs (PMICs) with even higher efficiency are essential. In many mobile products the PMIC cannot provide all of the necessary voltage rails, so standalone voltage regulators are also required. Needless to say, space is at a premium. All ICs designed for mobile today need to offer extremely tiny solution sizes.

Our industry leading, highly integrated PMIC and power SoCs are ideal for smartphones and tablets. Please contact a Maxim Sales Representative for more information about Maxim’s latest PMIC technology for smartphone and tablet power applications.

We also offer small footprint switching regulators and LDOs for mobile applications.

Smartphones require enhanced audio technology to achieve high quality audio. Two of the primary components include noise cancellation for improved listening in noisy environments and high power audio output for a more enjoyable speakerphone and music listening experience. Our high-performance, low-power stereo audio codec ICs improve loudspeaker performance while preventing speaker damage. Our speaker amplifier ICs combine superior sound quality with technological advancements that simplify the design process, save space, extend battery life, and reduce system cost.

Our patented Dynamic Speaker Management (DSM™) technology overcomes challenges presented by micro speakers. DSM creates a much louder and richer sound experience compared to conventional technologies.
