There are only a limited number of switching regulators designed to generate negative output voltages. In many cases, it’s thus necessary to use a switching regulator that was actually designed for a ...

Designers frequently use linear regulators to postregulate switching-regulator outputs. The benefits of this approach include improved stability, accuracy, and transient response, along with lower ...

A comprehensive understanding of switching regulator noise is important when designing a low noise switching regulator, says Leo Liu. Generally, traditional switching regulators are considered noisy ...

Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...

It couldn’t be simpler but you have to admit that a small adjustable portable power supply like this one will be really handy. The main part of the PSU is an LM317 linear voltage regulator which we’re ...

Intersil Corporation announced the ISL8002B synchronous buck (step-down) switching regulator that delivers up to 2A of continuous output current from a 2.7V to 5.5V input supply. Intersil Corporation ...

A topology for a single-inductor, multiple-output (SIMO) switching regulator was thesubject of a paper from two Hong Kong universities in the analogue techniques session atISSCC. In SIMO regulators, ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

Switched Capacitor (SC) DC-DC converters are DC-DC switching regulators that use only capacitors and switches to transfer charges between the input and the output. This architecture is an alternative ...

The LTM4644 integrates four separate constant frequency controlled on-time valley current-mode regulators, power MOSFETs, inductors, and other supporting discrete components (Fig. 1). Each of the four ...

Switch-mode power supplies switch with a frequency that is either fixed, adjustable, or synchronised to an external clock. The value of the switching frequency determines the physical size and, ...
