Requiring few external capacitors and no inductors, the TPS6050x charge pumps allow for a complete converter to be built in an area measuring just 0.155 in.2. With a quiescent current of 40 µA, the ...

Maxim introduced the MAX1578/MAX1579, the first complete LCD bias and white-LED power supplies with only one inductor and no charge-pump diode. Four regulated outputs supply all the voltages required ...

Fig 1. The standard Howland Current Pump (HCP) is a current source that can generate both positive and negative current. Fig 2. Adding a boost circuit to an HCP design allows for higher output current ...

Inductors are not the most common component these days and variable ones seem even less common. However, with a ferrite rod and some 3D printing, [drjaynes] shows how to make your own variable ...

Radio amateurs often have a love-hate relationship with home-made inductors, sharing all kinds of tips and tricks as to how the most stable nanohenry inductor can be wound. But there’s another group ...

In the race for ever-improving technology, there are two related technical capabilities that drive our world forward: speed and size. These are related, as the smaller a device is, the less distance ...

Linear Technology Corporation announces the LTC3214, a fractional charge pump, high current white LED driver that delivers up to 500mA of LED current. Its high efficiency multi-mode architecture ...

Smaller is better when it comes to microchips, researchers said, and by using 3D components on a standardized 2D microchip manufacturing platform, developers can use up to 100 times less chip space. A ...
