Switching regulators with integrated power transistors provide simplicity, require few components, and make compact step-down power supplies. Few of these devices can supply more than 5A load current, ...

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 ...

This circuit uses a step-up switch-mode regulator, which is usually used to produce a positive supply, to generate a regulated negative output voltage. The device used here is the MIC4680 from Micrel, ...

[Karl Lunt] is working to slim the Raspberry Pi current draw as much as possible. The first step in his journey was to replace the linear voltage regulator with this switch mode version. It’s a ...

Fig. 1. The LTM4623 is housed in a 1.82mm LGA package. Fig. 2. The package contains the switching controller, power FETs, magnetics and support components. Fig. 3. Simplified block diagram of the ...

Emerging as the industry’s first high-voltage, monolithic two-switch forward dc/dc regulator, the LM5015 sports an ultra-wide input voltage range from 4.25V to 75V and a maximum switching frequency to ...

These are partly line-bound at the input side and output side of the voltage converter, but partially these are also radiated. Those interferences are mainly caused by the rapid switching edges. They ...
