This 7-part series discusses tips and best practices for selecting the appropriate components for your switching power supply.
Explore several subtle nuances to significantly improve power supply performance. Examples include: the hidden advantages of synchronous regulators, a module that features the best attributes of a switcher AND an LDO, and tips to reduce system noise by manipulating output capacitor combinations.
EMI (electromagnetic interference) mitigation is a critical step in the design process in most electronic systems, and especially so in the automotive world. In many cases, automotive OEM emissions requirements are even more stringent than both national and international standards bodies like the FCC. Unfortunately, by their nature, switching regulators are sources of EMI; but, in order to keep power supply designs small and efficient, switchers are a critical component. So how can you reap the benefits of a switching regulator while still meeting challenging EMI requirements?
Certain end-equipment, like communications, server, industrial, and personal electronics have design challenges solved by the DC/DC converter’s control-mode. This session will compare and contrast 3 different devices using 3 different control modes under the same design criteria to see how each control mode solves particular size, efficiency, external component, ripple and transient response design challenges.
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.
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.
