Abstract This power management tip introduces the two different circuits for a positive-to-negative voltage conversion and for a negative-to-positive voltage conversion. It explains how a step-down (buck) regulator circuit may easily be modified to ...

We regenerate these type of alkaline batteries [1] here: (not normal rechargable ones ) The schematic The schematic is rather trivial (Fig. 1). A voltage regulator brings down a supply voltage (which might be from a car battery) to 5 V. An ...

Particulate matter (PM2.5) monitoring is a key public-health metric. Vehicle- and drone-mounted sensors can expand coverage, but many existing systems are too costly for broad deployment. This Design Idea (DI) presents a prototype PM2.5 sensing and ...

The Ćuk topology is ideal for generating a negative output voltage from a positive supply voltage. Negative voltages are needed in many systems to enable useful readout of signals from certain sensors. For this, a signal chain may need to be ...

I’ve recently published Design Ideas (DIs) showing circuits for linear PWM programming of standard bucking-type regulators in applications requiring an output span that can swing below the regulator’s sense voltage (V SENSE or V S ). ...

Our fundamental passive and inherently analog components resistors, capacitors, and inductors are so conceptually simple and easy to describe that we often don’t fully articulate or appreciate the many roles each can play in a system or ...

Abstract This article will explain the inherent limitations of the boost topology and how to overcome them. When designing and evaluating boost converters, sometimes the intended output voltage is not realized. Instead, it has a lower value than ...

Introduction A switching regulator converts an input voltage to a higher or lower output voltage. For this, an inductor is used to store energy temporarily. The size of this inductor depends on the switching frequency of the switching regulator as ...

Solar-photovoltaic arrays seem to get cheaper and more efficient every day, making them increasingly practical in renewable and/or remote power supply applications. Still, the voltage generated by any given array varies significantly with loading, ...

Minimizing noise is a common challenge for engineers designing a power supply for noise-sensitive systems for test and measurement and radio applications, such as clocks, data converters or amplifiers. Although the term “noise” can mean ...
