This article was prompted by a friend of mine asking for help on a board with an ESP32 heart. The board outputs 2.1 V instead of 3.3 V, and it doesn’t seem like incorrectly calculated feedback ...

When considering how best to lay out a switching-regulator board, it's good to recall its purpose, which is to supply a steady voltage of a specific magnitude. Experienced layout designers achieve ...

A golden power supply that will satisfy every design requirement does not exist. Size, cost, and efficiency are the driving factors for selecting a design, causing each design to be different. This ...

If you are an electronic engineer or received an education in electronics that went beyond the very basics, there is a good chance that you will be familiar with the Fairchild μA723. This chip ...

Feedback-control schemes for linear systems have been around since at least the 17 th century, regulating pressure and distance between millstones and then, famously, to control James Watt’s steam ...

One question that comes up regularly is how to generate a tiny dc supply voltage of a few hundred millivolts. The answer is relative straightforward: All that’s needed is a clean additional positive ...

DC/DC point-of-load switch mode regulator Circuit with spread spectrum frequency modulation can be designed for low EMI, write Alan Chern, Doug La Porte and Afshin Odabaee Switch mode DC/DC regulators ...

DC-to-DC switching converters are widely used in most portable devices. They efficiently generate various regulated supply voltages for different sub-blocks within the same system board. A typical ...

Low dropout (LDO) regulators play a very important role in the power management of an integrated circuit. As a result, mindful designing and selection of LDO circuits become crucial. This article ...

Designed as cost-effective drop-in replacements for LM78xx linear regulators, the K78-LB series by Mornsun is available from Relec Electronics. The K78xxJT-500R3-LB and K78xx-500R3-LB (K78-LB) family ...
