Comparing A/D Power management techniques By don caron CHiL Semiconductor Tewksbury, MA http://www.chilsemi.com Contents Viewpoint Selecting the Right dc/dc Converter Selecting the Right Battery System Understanding the Buck Switchmode Power Converter Analog news Recent advances in digital power control offer help for achieving high power efficiency not available with typical analog methods T o manage power in higher-performance servers, PCs, and graphics cards, designers have typically relied on traditional analog approaches to power management. Managing, monitoring, and controlling efficiency is one of the most significant differentiating factors as IT managers struggle to rein in escalating energy costs in data centers. But managing the power for the latest low-voltage, high-frequency processors, graphic processing units (GPUs), and memory modules creates a host of new problems. Since these CPUs transition from low to high current at rapidly rising rates, designers need to implement extremely tight and accurate power regulation to handle these fast transients. Designers using traditional analog schemes have relied heavily on techniques that require large numbers of external components in their control loop to ensure compliance.
