t-60 space grade video training series

T-60: Space-Grade Design Video Training Series

The T-60 series will give an overview on overcoming technical and design challenges in space grade power designs, from basics on qualification and radiation to more complex topics around power design techniques.

The series will be divided into specific themes, each of which will contain multiple sub-topics around different areas of space-grade design. Learn the basics of Qualified Manufacturers List Class V (QMLV), flow and qualification, as well as how to address low voltage power design challenges related to FPGAs, ASICs, SoCs and precision analog. 

Understanding the fundamental technologies of power density

The need for improved power density is clear, but what limits designers from increasing power density today? Watch this five-part training series where we outline how to achieve higher power density by examining four critical aspects of high-power-density solutions, as well as relevant TI technologies and products supporting these specific requirements.

Power-Conversion Techniques for Complying with Automotive Emissions Requirements

Power Conversion Techniques for Complying with Automotive Emissions Requirements

Comité International Spécial des Perturbations Radioélectriques (CISPR) 25 is the typical starting point for evaluating conducted and radiated emissions in automotive systems. This topic addresses the unique challenges of designing power converters to pass CISPR 25 requirements, including background information on the CISPR 25 standard and test setups. We explain common noise sources in power converters and various techniques to reduce conducted and radiated emissions, including input filter design, frequency selection, mode selection, snubber design, shielding and layout.

Application-Specific EMI Considerations

Some systems simply require more attention than others when it comes to EMI. In this section, we will examine some of those specific end applications and provide some helpful hints to reach EMI targets with each.

EMI: The Fundamentals

Before we dive into specific application-based examples of noise and EMI mitigation, let's start with the basics. What is EMI? How is this different from noise? What is ripple? How are they measured? What are some common approaches to limiting their effects? This section discusses these topics with a more conceptual approach to serve as a primer for the rest of the series.

Enhancing power supply performance with the TPSM53604 power module

Reducing power supply solution size has traditionally come at the expense of reduced efficiency and thermal performance. But with TPSM53604 and its Enhanced HotRod™ QFN packaging, this is no longer the case. See how you can leverage the TPSM53604 in your next design to buck the trend and set a new bar for power module size and performance.

Reducing EMI via considerations external to the IC

For many engineers, layout for EMI mitigation is a black art. It may seem like the slightest adjustment could be the difference between passing or failing CISPR standards. Because of this, some power designers may shy away from using devices with switching elements as a guaranteed way to avoid the headache of reducing emissions. But this may be trading one problem for another, as switching devices generally have better efficiency and thermal performance.

Modules EMI

Reducing EMI through device selection

Efficiently addressing EMI starts at the device selection stage. On-silicon technologies like spread spectrum or unique packaging approaches like HotRod™ QFN can help reduce EMI before we even begin the discussion of component layout and filtering.

Low EMI

Designing a Low EMI Power Supply

Mitigating EMI is seen by engineers as a black art. Choose the wrong feature set - or mess with the feng shui of the PCB layout too much - and the system may not pass stringent CISPR standards. 

This training series - along with all of the accompanying documentation - is an aggregation of reference materials showing engineers an easier path to design an efficient power supply that meets EMI requirements.

Voltage Regulator Design and Optimization for High-Current, Fast-Slew-Rate Load Transients

Designing to the tight voltage tolerances of today’s modern central processing units and field programmable gate arrays (FPGAs) is becoming more difficult as their current draw increases and becomes more dynamic. Getting the correct output capacitance mix to ensure first-time power-delivery success is no small feat with >100-A steps and slew rates in excess of 100 A/µs. Standard point-of-load design techniques no longer hold true; we need new methods to choose the output capacitance.
