ISIL Intelligence Systems Integration Laboratory (Ft. Huachuca, Arizona; US Army facility for integrating intelligence systems) 
), a leading systems-oriented provider of ICs and semiconductors for the integrated communications market, announced the inaugural device in a family of power management integrated circuits Integrated circuits

Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1.
 (ICs) specifically developed to power next generation, high performance mobile products. Intersil's new portable power management devices are designed to increase battery life in the newest, most compact wireless and mobile devices.

Information retrieval and manipulation in mobile computing environments has created a demand for next-generation products that allow users to access Intranets, networks and the Internet at speeds rivaling desktop PCs. In this environment, power management becomes a critical element in successful system design. Advanced microprocessors demand more energy on a dynamic basis while the physical size of the portable information appliances continues to shrink, allowing less room for power management and thermal management devices.

Intersil's first portable computer power management device efficiently regulates system energy usage and directly contributes to extended battery life. Specifically, Intersil's architecture allows the central processing unit See CPU.

(architecture, processor) central processing unit - (CPU, processor) The part of a computer which controls all the other parts. Designs vary widely but the CPU generally consists of the control unit, the arithmetic and logic unit (ALU), registers, temporary buffers

) voltage regulator to be completely turned off when the microprocessor is not in use, eliminating voltage generation for the CPU and reducing total system power consumption in aggressive mobile power management environments. This device automatically adjusts pulse width modulation See PWM.  (PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a ) outputs to meet reduced current requirements in lower power sleep states, and these outputs can be individually turned off to further reduce power consumption. PWM is a high-frequency energy processing operation that is performed on the interverter-switched output voltage or current waveform to optimize performance.
