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 ...

It never fails — we post a somewhat simple project using a microcontroller and someone points out that it could have been accomplished better with a 555 timer or discrete transistors or even a couple ...

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 ...

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 ...

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 ...

There have been many articles describing the use of multiphase buck converters, especially for high-performance point-of-load applications. However, all the advantages of interleaving, such as higher ...

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 ...
