Let's say I have an array of many indicator LEDs that I need to turn on/off independently; the LED current is about 1 mA. In the past I used constant sink LED driver ICs such as the TLC5916 as shown below. This worked very well. Now it looks like such ...
The driver must have a higher output power than your LEDs require for extra safety. If the output is equivalent to the LED power requirements, it is running at full power. Running at full power may cause the driver to have a shorter life span. Similarly the power requirement of the LEDs ...
I would like to be able to adjust the current through the LED from 10mA to 100mA. For that, I am planning to use the trimmer resistor in series with a 10 Ohm resistor in place of the Rext, where the 10 Ohm on its own will drive the Iout to about 90mA, and additional resistance...
The Back Soldering of Our LED Drivers That is very vital that a factory should have a perfect QA and QC system for the parts and the complete testing of the LED Drivers, I would like to bring our boqi LED Driver as an example, see how we guarantee the quality of each led driver. 1...
How to implement small LCD backlighting--LED driver considerationsOver the last several years, small color LCD displays have been integrated into an ever-broadening range of products. Color displays, once considered a luxury in cell phones, are now a standard offering even at the entry level. ...

We are approaching a new era of driving, where we will increasingly witness a move towards shared driving responsibilities between the human driver and the vehicle. Although remarkable technological improvements and public health efforts led to a decline in motor vehicle fatalities in the past two de...
In the Arduino IDE, go to Tools->Optimize->Debug. This will include -g in the compilation process, including debug symbols Connect the stlink probe to the board and the computer. I am assumingstlink driveris already installed. If it is the first time you are using the Stlink dongle, ...
For common cathode RGB LEDs, a current source LED driver is necessary. In general, common anode LEDs are more popular, as NFET can sink more current than PFET can source in the same area, so a smaller size driver for common anode LEDs can be used for the same current supply. But ...
