Based in Sunnyvale, CA, Advanced Analogic Technologies, Inc. (AATI) engages in the design, development, marketing and sale of power management semiconductors. It supplies power management semiconductors for mobile consumer electronic devices, such as wireless handsets, notebook and tablet computers, smart phones, digital cameras, and personal media players. The power management semiconductors deliver power and regulate voltage, controlling the flow of electrical energy among the various power loads and energy sources in a product or system. These semiconductors are designed primarily as analog circuits to support a wide and continuous range of input and output voltage and current.
Semiconductor devices are broadly divided into three categories: analog, digital and radio frequency (RF). Analog semiconductors condition and regulate real world information such as light, temperature, speed, pressure, power and electrical currents. Digital logic semiconductors process information in only two states. Mixed-signal semiconductors combine both analog and digital technology into a single device. Typically, an analog sensor samples real world information, and then converts the input into an electronic analog signal, which is converted into a digital format for further digital processing. The analog and mixed-signal markets tend to be more varied and specialized, with customized products that have longer life cycles than those in the digital industry segment. There is an ongoing drive to decrease the number of discrete devices, lessen power requirements and shrink the size of the existing devices, which correspondingly increase performance and reliability. Consequently, a greater amount of functionality is being consolidated into increasingly smaller devices. The Gartner Group estimated that the total worldwide semiconductor market was a $219.9 billion market in 2004. The analog market component grew 29% in 2004, to a $36.4 billion market, according to In-Stat, an industry trade group.
Utilities transport electrical energy using an alternating current (AC) scheme, which minimizes energy loss. Semiconductor ICs require direct current (DC) power sources in order to operate, thus the AC power must be converted or transformed into DC. POWI's product line of ICs control, condition or convert electrical energy into a form that can be used to power various devices. The ICs are utilized by other OEMs in alternating current (AC) to direct current (DC) converters, and more recently, in DC-to-DC converters. Power Integrations was a pioneer in the development of a cost effective high-voltage integrated switcher product line that replaced the legacy discrete switchers in the 1990's.
The company offers a portfolio of approximately 480 power management products, comprising power management application-specific standard products and selected general-purpose analog ICs in single-chip and multichip packages. Advanced Analogic Technologies sells its products through its direct sales and applications support organizations, as well as through distributors to original equipment manufacturers, original design manufacturers, and contract electronics manufacturers
