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 extends battery life up to 400%. 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.
