Why should you understand power management?
In today’s computing environment, CPUs, FPGAs, ASICs and even peripherals are growing increasingly complex and, consequently, so do their power delivery requirements. To handle the higher demands, multiphase regulators are becoming increasingly common on motherboards in many areas of computing--from laptops and tablets to servers and Ethernet switches. Designing with these regulators is more challenging than using conventional switchers and linear regulators, but the benefits of multiphase outweigh the complexity for high-performance power applications.
Managing heat dissipation has always been a critical concern for any power supply designer, and this concern has only grown in importance as output current levels have increased while IC package sizes have gotten smaller. This page serves as your ultimate resource for all training materials and technical documentation related to keeping your switching regulator running cool.
There are numerous ways to address thermals. This library of training content is broken out by some of these key approaches to improving the thermal performance of your switching regulator.
As switching converters have evolved, they have taken on a host of new features to operate more efficiently and quietly. To some, however, all these new features listed on the front page of the datasheet may seem foreign. This training series dives into those features to explain the true benefits of each and help you decide which are necessary for your power supply design. Specifically covered in this series are the buck converter topics of:
Battery life cycle is a key for high-cell-count battery pack-based end-equipment. Low quiescent current (Iq) consumption of DC-DC converters is a major feature that helps achieve longer battery life cycles. TI’s latest buck converters boast low Iq consumption as they maintain high efficiency in the active mode (heavy loads) as well as extend battery life during standby modes. This training will cover an overview of battery powered industrial applications and the specific power consumption requirements for these end equipments.
This is a qualitative overview of the control of Switched Mode Power Supplies.
For noise-critical portable applications, such as GPS receivers, connectivity, and sensing, power supply designers always had to choose between longer battery run time (from higher efficiency) or higher signal chain performance (from the increased sensor sensitivity possible with a quieter power supply). For line-powered industrial or communications equipment applications, designers have been forced to dissipate significant amounts of power in LDOs to achieve the desired noise performance. Achieving both low noise and high efficiency was impossible.
