Keeping Pace with Power Hungry Mobile Devices
Battery life and thermal budget are two of the most critical factors challenging engineers designing mobile power management systems. As mobile device hardware and software capabilities have increased, so have the peak power requirements from the voltage regulators that supply power to these systems. While most power requirements are already integrated into a smartphone and tablet’s power management IC, discrete power solutions must also keep pace with the next round of mobile system innovations. This white paper discusses the challenges of increasing a mobile product’s power efficiency, and shows power system designers how to use next generation buck-boost converters to increase the life of Li-ion or Li-polymer batteries.
