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 ...
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 ...
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 ...
Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate 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 ...
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 ...
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 ...
