When designing a handheld device with a colour display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

Light-emitting diodes are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the constant-current ...

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for ...

LEDs are more efficient than incandescent lights and can last 100 times longer, but they require specialized electronic-drive circuits to avoid overstress conditions. The main operating parameter is ...

LEDs are a staple component in most circuits. Using Ohm’s law, we can easily calculate the conditions for the theoretical lighting intensity we’re after. LEDs are a staple component in most circuits.

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

If there are no branches then it's a series circuit. If there are branches it's a parallel circuit. In a television series, you get several episodes, one after the other. A series circuit is similar.
