Consumer demands for functionality
continue to increase

People are buying electronic devices at a rapidly increasing pace. And, they continue to expect more features in smaller, sleeker devices. For example, mobile phones now take pictures, surf the Internet and play music.

Consumers are demanding more functionality, but battery life continues to be a customer satisfaction issue. To address dissatisfaction with battery life, Packet Digital developed its patented On-Demand Power® technology and PowerSage™ integrated circuits.

Packet Digital understands that energy in an electronic system is best used only when and where it's needed. By taking a real-time systems approach to power management, Packet Digital developed its patented On-Demand Power technology and PowerSage, an intelligent integrated circuit that monitors an entire system and distributes power only when needed by using dynamic frequency and voltage scaling. Through this innovative approach, PowerSage significantly extends battery life in portable electronic devices.

PowerSage significantly improves the performance of systems in many applications, such as cell phones, laptops and digital music players. Additionally, PowerSage can replace multiple components - driving reductions in device cost, weight and size.

PowerSage crosses traditional power management boundaries by:

• Regulating voltage in a single power management unit, or in distributed components
• Managing power sequencing
• Providing "power good" and "power soft" reset indicators
• Ensuring power integrity
• Managing sleep and standby modes and providing clock and power gating
• Offering independent or coordinated dynamic voltage and frequency scaling

Beyond reducing power consumption, PowerSage systems produce less heat, decreasing the need for cooling components which consume space and battery power. In addition, Power Sage systems produce less radio noise, which benefits the cell phone industry by expanding signal-to-noise ratios.

PowerSage offers advanced power management across platforms, operating systems, and devices, including digital music players, laptops, mobile phones, cameras and ultra mobile PCs. PowerSage:

• Monitors activity across an entire system, delivering power only when needed
• Controls clocks and supply voltages in real-time, system-wide, outside the microprocessor
• Reduces the costs, weight and size of consumer electronic devices
• Decreases time-to-market based on intelligent power design
