This is the circuit diagram of bipolar LED Driver using microcontroller. Here we use an LED which has a forward voltage drop of 2.2V and hence can be biased using a 5V supply. This Bipolar LED Driver ...

Santa Clara, Calif. — National Semiconductor Corp. has designed a Boomer light emitting diode (LED) driver that provides audio synchronization without real-time software processing. The LM4970 LED ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...

Nearly all lighting applications today use LEDs. In a relatively short amount of time, they have become established as the preferred choice of illumination. However, in most applications, an LED can’t ...

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 ...
