Using an LDO vs. Switching Regulator in Your PCB

As much as we’d like, the power we supply to electronics isn’t always stable. Real power sources contain noise, they might exhibit power instability, or they dropout unexpectedly. Thankfully, we have power regulators to help prevent some of these problems. For low power devices, we generally see two types of power regulators: a low dropout regulator (LDO) or a switching regulator. You can mix and match these at different points along your power bus, but there’s still the matter of choosing whether to use an LDO vs. a switching regulator in your designs.

Using Altium 365 for Sharing Simulations in the Cloud

Post-layout simulators for your PCB are very valuable tools. If you’re working through a complex design, it’s a good idea to put it through some level of simulation and analysis to evaluate the design before manufacturing. This is all easy with the cloud collaboration tools in Altium 365 and Ansys field solvers thanks to the EDB Exporter utility in Altium Designer. These existing tools in Altium Designer and any of the Ansys field solver utilities give you a simplified way to share design data, EDB files, and simulation results with anyone on your design team.

How to Speed Up Your DFM Report Process in the Cloud

Experienced fabricators will tell you: any design could have some hidden DFM problem that will interfere with manufacturability, quality, or yield. Making use of your design rules is just the start of preventing DFM problems, you’ll want to collaborate with your manufacturer throughout the design process if you want to spot and correct DFM problems. Within Altium Designer, there are multiple reports you can generate for your projects that will help you summarize important information on your board for a client or a manufacturer.

The Digital Engineer's Guide to RF PCB Layout and Routing

With modern systems running at higher frequencies, incorporating multiple wireless protocols, and interfacing with many analog sensors, advanced designs require knowledge from digital and RF design disciplines. If you’re now starting to work in the RF realm and you need to design an all-analog or mixed-signal system, RF PCB layout will need to become a new specialty. If you’re a digital designer and you’re now jumping into high-frequency analog design, keep reading to learn more about RF PCB layout and routing.

Microstrip Ground Clearance: How Close is Too Close?

If you take a look at any guidelines for controlled impedance traces, you’ll clearly see that the trace width is calculated without any ground pour near the trace. However, most designers will state that unused areas on each PCB layer should be filled in with grounded copper pour. If you bring some ground pour near a microstrip, you’ve now formed a coplanar waveguide arrangement. So now the question becomes, how much microstrip to ground clearance do you need to ensure you’ve hit your impedance goals?

PCB Layout Guidelines for Switching Power Supplies and Regulators

In this article, I want to briefly focus on how power supplies and regulators are different, although this should already be clear to most designers. For a power supply and for a PCB with an on-board regulator, the switching regulator layout will be a major determinant of overall system performance. Therefore, we’ll largely look at some layout guidelines for switching power supplies in terms of regulator layout.

How to Combat Power Supply EMI in Your PCB

Power supplies are one of those systems we all tend to take for granted. Everyone’s first task in power supply design is usually to ensure the voltage and current output reach the desired level, probably followed by thermal considerations. However, due to safety issues, EMC requirements, the use of higher PWM frequencies, and the need for smaller packaging, power supply EMI should be a major design consideration. With that being said, what are the major sources of power supply EMI, and how can power supply designers keep them in check?

Leveraging the Free Footprint Community to Design at Lightning Speed

Designing footprints is a job most people hate. It’s tedious, time-consuming, and doesn’t result in much except, well, a footprint. Companies now realize this pain point and offering designers free, well-designed PCB footprints. Why would they spend their time doing this? In this article, we’re going to review some of the free offerings that exist within the PCB design community. Once you’re armed with this information, you will spend most of your time designing and routing boards instead of pulling your hair out creating footprints all day.

What They Don’t Teach You About Fluxes

PCB fabrication is an extremely complex technological topic that deserves recognition as the most fundamental part of PCB engineering. Unless connectors, conductive adhesive, wire-bonding, or zebra-tape are used, in the modern electronics industry it’s always necessary to use some kind of flux during the soldering process to create an electric connection. In this article, we’ll discuss fluxes — what they are, what they are made of (yes, there is going to be a lot of chemistry, don’t be scared), how they should be used, and in what direction the industry is going.

Thermal Management for Integrated Circuits

As anyone who designs and builds electronic devices knows, the device will generate heat when it’s switched on. Wherever current flows through an impedance, energy losses will manifest themselves as heat. Integrated circuit packaging is getting smaller to meet the trend for more compact devices but at the cost of poorer thermal properties. This article describes the basic thermal management approaches to consider in your next designs.

Anatomy of Latitude Part Two: "Thread with a Needle” in the context of energy

We continue to explore the magic of energy conversion in a PWM transducer. Why is it magic? Theoretically, in a PWM transducer this happens without losses, isn't that magic? A PWM transducer, like a tailor with scissors, cuts the “fabric of energy” into pieces, and then, like a sewing machine, stitches the pieces of energy into a dress - DC Magnitude. What is a constant component and how can we get it? Let's explore!

How to Select Copper Foil for High-Frequency PCB Design

The PCB materials industry has spent significant amounts of time developing materials that provide lowest possible signal loss for products with RF applications.

Why Most Via Impedance Calculators Are Inaccurate

The problem with every via impedance calculator that I have seen is simple: they are incomplete or totally wrong. The “incomplete” part refers to a lack of context; these calculators can roughly reproduce a well-known estimate from a legend like Howard Johnson in his Digital Design textbooks. However, these calculators never provide insight into what they are actually calculating, or where the calculated via impedance is accurate. Keep reading to see why these calculators get it so wrong, as well as the context surrounding via impedance.

Buck Converter Simulation in Altium Designer

When designing high power circuits (usually very high voltage and/or current), you’ll need to create a regulator from scratch and place it in your PCB layout. It's also the case that you may want to model a real component using discretes in a simulation in order to qualify the system's expected operating regime. As part of buck converter design, you can easily run a buck converter simulation directly in Altium Designer’s schematic editor.

SPI vs. I2C: How to Choose the Best Protocol for Your Memory Chips

One of the common implementations of SPI and I2C in a PCB layout is as a protocol for reading and writing to an external Flash memory. Flash chips are a very common component in embedded systems and can offer high capacities of non-volatile memory up to Gb values. When choosing a memory chip, you'll want to match the application requirements and functionality with the bus speed you need for read and write operations in your memory chip. There is also the matter of the type of Flash memory you'll need to access (NOR vs. NAND).

Is There an SPI Trace Impedance Requirement?

There is no SPI trace impedance requirement? The reality is that SPI lines only start to need impedance control when the length of the interconnect becomes very long. And because there is no specific impedance requirement in the bus, you have some freedom in channel design and termination. So what exactly qualifies as “very long” and when is some termination method needed? We’ll break it down in this article.
