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 ...

Internal operating voltages in electronic devices continue to decrease, but input-source voltages don't change. As the difference between input and output voltages increases, so does the improvement ...

Analog Devices, Inc. introduced the ADP2323, a 20-V, 3-A dual output DC-to-DC regulator featuring a high conversion efficiency of greater than 93 percent. Analog Devices, Inc. introduced the ADP2323, ...

Fairchild Semiconductor developed the FAN5358, a 2MHz, 500mA, synchronous Buck regulator that meets the design challenge of portable devices, especially smartphones, data cards and tablets. Fairchild ...

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 ...

Some time ago, while designing the PCB for the Sony Vaio replacement motherboard, I went on a quest to find a perfect 5 V boost regulator. Requirements are simple – output 5 V at about 2A , with input ...

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 ...

Mathieu Renaud, Senior Power Management Designer, Intégration Dolphin Inc. Yves Gagnon, Executive Director, Intégration Dolphin Inc. Inductor-based Switching Regulators (SR) have historically ...

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, ...

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 ...

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, ...

Said to consume just 150nA of supply current, the TS3310 dual output boost regulator from Touchstone Semiconductor is designed to extend battery life by minimising the impact on a device's sleep ...
