Power Management Solutions

In January 2012, Skyworks completed its acquisition of Advanced Analogic Technologies, Inc. (AATI), an analog semiconductor company focused on enabling energy-efficient devices for consumer electronics, computing and communications markets. This acquisition expands Skyworks' portfolio with highly complementary analog semiconductor products including battery chargers, DC/DC converters, voltage regulators and LED drivers. It also enables Skyworks to further capitalize on its strong smart phone, tablet, set-top box, infrastructure, automotive, aerospace defense, connected home, smart energy, and medical positions with an expanded and differentiated product portfolio while accelerating entry into new vertical markets.


Battery Chargers

Battery Management products are TPMICs (Total Power Management ICs) that manage the charging, sequencing and protection of lithium-ion/polymer batteries in personal portable electronics. Skyworks' linear and switching chargers are designed for single and/or dual cell lithium-ion/polymer batteries. These full-featured battery management ICs maximize charging speed and minimize power loss during power delivery to the system. Additionally, they offer integrated system protection using USB and/or adaptor input and dynamic charging capabilities. Many of these products contain unique circuit features to provide advanced IC thermal management during charging and proprietary input power control when supplied from USB port sources. New additions to this product line also feature over voltage protection up to 28V.

Voltage Regulators

Skyworks’ high efficiency pulse width modulation (PWM) switch-mode voltage regulators are ideal for a wide variety of products such as smartphones, PNDs, notebook computers, set-top boxes, digital still cameras, and other portable electronic devices. Solutions are available for a wide range of output power, optimizing both size and performance for specific power levels. The switch-mode products utilize high switching frequencies to minimize output inductor and capacitor size. Internal compensation eliminates additional external components. These products provide excellent light load efficiency and minimum light load ripple. In addition to excellent efficiency, many SwitchReg™ products offer fast turnon time and fast transient response capabilities. Taking advantage of advanced modular bipolar CMOS DMOS (BCD) processes allows very low resistance switches and eliminates the need for special packages that require additional thermal relief.

Display & Lighting

Skyworks offers a wide variety of boost converters and charge pumps for display and lighting products. Typical applications include white and RGB LED drivers for display backlighting, fashion lighting, as well as camera flash and movie mode plus panel bias for OLED displays. For color display and keypad backlighting, Skyworks offers a family of charge pump products for driving and controlling the current (brightness) in white LEDs. Utilizing a proprietary protocol with a patented AutoBias tri-mode charge pump, these low-noise, small footprint products can control LED brightness with a single control wire, eliminating the need for PWM signals. These devices also reduce component count by removing the requirement for external ballast resistors. Application-specific charge pump products are also available for driving color RGB diodes, camera flash diodes, and TFT biasing.

Power Half Bridges

Skyworks’s Power Half Bridges include MultiMHz power switches that can be used to provide compact voltage regulation in high-speed power supplies. Integrating input level shifting, high-speed break-before-make (shoot-through protection) circuitry, and low resistance, these power MOSFETs reduce board space, parts count, and stray parasitics in switching power supplies. FastSwitch™ buffered half bridge products may be used to drive inductors directly, as high-current gate drivers for discrete power MOSFETs. In addition, a dual buffered half-bridge may be used to drive multiple outputs or can be configured as a full bridge to affect a DC motor or Class-D audio driver.

Current Limited Load Switches

Current Limited Load Switches are designed for high-side power switching applications to cover a wide range of port protection applications for USB, PCMCIA (PC cards), and IEEE 1394 (FireWire) ports in desktop and notebook computers. Port protection switches provide inrush current limiting, short-circuit and overtemperature protection, input control level shifting, and fault flags. Designers can select different current limit options from preset thresholds to user-adjustable limits using just one external resistor. Single, dual, and quad switches are available to fulfill a wide array of application requirements. Devices intended for USB applications have complete Underwriters Laboratories® approval.
