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 ...

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 ...

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 ...

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 ...

The Kobe University-developed direct current voltage boost converter has much reduced electromagnetic noise and a high energy efficiency of over 91 percent, which is unprecedented for a MHz drive with ...

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 ...

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 ...

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 ...
