Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

Electronic circuit designs often require power sources with negative output voltages. There are many different ways of producing a negative output voltage from a positive input voltage. One option is ...

DC to DC conversion has come a long way. What was once took an electromechanical vibrator and transformer has been reduced to a PC board the size of a largish postage stamp that can be had for a ...

Linear Technology Corporation introduces the LTM8045, a 2.8V-18V input, multi-topology DC/DC µModule® (micromodule) converter, with onboard inductor, power switch and DC/DC controller delivering up to ...

Buck-Boost DC-DC Converters are versatile power electronic devices that facilitate the conversion of a direct current (DC) input to a DC output that may be either higher or lower than the supply ...

4.6 to 5.0V (VPOS) with 0.5% accuracy at up to 500mA from a buck-boost converter-1.4 to -5.4V (VNEG) with 0.5% accuracy at up to 500mA from an inverting buck-boost converter 5.8 to 7.9V (AVDD) with ...

This represents one of the three elementary switching regulator topologies and requires only two switches, an inductor, and input and output capacitors. Besides the boost converter, the other basic ...

Most common electronic devices require an input voltage source to operate. The voltage source may be a battery for portable devices, an AC line source for consumer electronics, or even a regulated DC ...

There comes a time in every hardware hacker’s career during which they first realize they need a negative voltage rail in their project. There also comes a time, usually ~10ms after realizing this, ...
