… That being said, it’s usually easier and about the same cost to just to throw a feedthrough cap (“three-terminal capacitor”) filter on the rail, unless you *really* need 40-60 dB filtering.

BJTs are usually thought of as current controlled current sources/sinks, FETs as voltage controlled current sources/sinks. Still, with a BJT you’ll need 0.7-1V or 1.4-2V (as someone else mentioned, check the graphs) to reliably handle the current you require. This follows the typical diode IV curve. Still, high power BJTs tend to have low hFE (Ic/Ib), perhaps on the order of 20-40. In a darlington arrangement, this current may not come from your MCU but it is still present as loss and additional heat. I feel the article is misleading. There are minimum base voltage requirements with BJTs too, it just happens to be lower generally, and does not have the options in threshold voltage you find with FETs. All normal silicon BJTs have similar, typical, base voltage requirements.

Also if the load voltage is around or below the gate voltage then the same setup can be used as high side switching.

The outage lasted four minutes, long enough to provoke thoughts about a system upon which we are deeply dependent, but know little about.

In the United States there currently are not enough fast charging stations. In total, there are 150,000 gas stations in the U.S., compared to 10,000 public EV charging stations, according to Canaccord Genuity.

Thanks for reading this article; you can also get individual chapter wise section or region wise report version like Asia, United States, Europe.

Steve Weir has a great presentation on this from 2009, but it’s partially lost to the depths of time (search for “Understanding Ferrite Beads and Applications 2009 weir ipblox” and you should be able to find copies of it). He’s got more recent talks on it too, although I always think he complicates things a little bit too much. It’s great to have full PDN simulations for everything, but usually cap + ferrite + cap + (5x cap+series resistor) will work well.

Muchos fabricantes en el mundo han adoptado el MC34063A entre sus productos líderes, gracias a la versatilidad de uso, facilidad de diseño y sus posibilidades de desarrollo. Este circuito integrado es básicamente un Convertidor DC-DC que puede manejar tensiones de entrada desde 3Volts (dos baterías AAA) hasta 40Volts, y puede cumplir funciones de Step-Up (elevación), Step-Down (disminución) e inversor de la polaridad de la tensión de entrada, entregando en la salida una corriente de switch máxima de 1,5 Amperes. Todo con muy pocos componentes sencillos a su alrededor.

Key companies profiled in Coil Wound Devices Market report are ABB, Honeywell International, Parker Hannifin, Danaher,. SIEMENS, Magnet-Schultz, Murata Manufacturing, Emerson, Schneider Electric and more in term of company basic information, Product Introduction, Application, Specification, Production, Revenue, Price and Gross Margin (2014-2019), etc.

I was just pricing out high-speed PCB’s made with Rodgers RO0435 material and the price was a significant portion of the cost of a CSA off of Ebay, lol.

I think most people’s problems when adding ferrites along the power planes is that “ferrite” isn’t actually a generic component. I don’t use ferrites that don’t have SPICE models, and I’d prefer them to have full S-parameter characterizations up through 1 GHz. Ferrites are really fairly complicated parts, and so the manufacturer recommending “cap + ferrite + cap” is really a recipe for disaster, because you probably don’t know what cap or what ferrite was used. They really should be specifying recommended attenuation at certain frequencies, or VCC frequency/noise masks (much like phase noise masks that certain manufacturers give on clocks).
