Several bias voltages are needed for supplying and operating an LCD panel. In most cases, specialised integrated circuits with several charge-pumps are used to generate the different voltages. As the ...

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 ...

Phoenix, Ariz.—ON Semiconductor has introduced the CAT4106, a 6W LED driver with an integrated, high-power DC-DC boost converter and on-chip diagnostics to maximize efficiency in larger, general ...

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 ...
