This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with many integrated analog features. The LED driver ...

The A6280 from Allegro MicroSystems Europe is a new 3-bit constant current LED driver which enables users to minimise ... manufacture and marketing of high-performance power integrated circuits and ...

All require constant-current ... draws no current (actually, in the 10-nA range) from the output. This isn’t true in the example circuit. The driver’s CAP pin and LED pin bias currents are ...

Figure 1 This circuit drives a string of LEDs with a constant current over the entire worldwide range of ac-mains voltages. The resistor in series with the LED string provides a convenient point to ...

Infineon has brought out a constant current linear LED driver IC which provides low-voltage drop performance ... a smart over-temperature controlling circuit keeps the current constant even at rising ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s ...

The architecture of a common constant-current, closed-loop-control LED driver circuit is shown in Fig. 1. In this and most other LED driver architectures, either switching or linear, the LED ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

“The demand for constant-current LED drivers that support ever greater number of LEDs with consistent LED brightness and color accuracy continues to grow,” said Ven Shan VP of Lumissil Marketing.
