Portable battery-operated electronic equipment is becoming packed with more features requiring larger amounts of power, leading to decreased operating times between battery charges. Innovations such ...

We have a love/hate relationship with LiIon batteries. They pack all this power in such a small and light package. But for running 3.3 V devices, they’re cumbersome. They need to be stepped down a ...

DC/DC converters are quite popular among electronic enthusiasts and are widely used within the industry. There are three major types of non-isolated DC/DC converters: buck, boost, and buck-boost. In ...

Many portable devices use LCD displays. These displays need large positive and negative power supplies, but most mobile devices have power rails at 5 V, 3.3 V or even lower. Thus, the challenge is not ...

STMicroelectronics’ L4985A/B and L4986A/B power-factor correction (PFC) boost converters look to simplify design and enhance flexibility by integrating 800V startup circuitry and additional valuable ...

A battery alone may not be capable of supplying complex systems with all the voltage rails necessary to function properly. Applications such as automotive LED drivers, audio amplifiers, and ...

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 ...
