In Part 1 of this two-part series, “Creating Uniform LED Luminescence in RGB Displays”, the discussion focused on dot correction. This design technique is used for managing individual pixel brightness ...

Maxim Integrated Products introduces the MAX16831 high-voltage, high-power, constant-current LED driver with analog and PWM dimming. This LED driver integrates a floating LED current-sense amplifier ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

Instructables user [Simon] admits he addicted to electronics. Lucky for him, his wife of 15 years is pretty cool with, or at least tolerant of his need to fiddle with anything that plugs in. As a gift ...

Most of us are aware that charlieplexing can drive a large number of LEDs from a relatively small number of I/O pins, but [David Johnson-Davies] demonstrates adding another dimension to that method to ...

Usually, an MCU is considered a digital device. By default, its output voltage level can be either high or low and nothing in between. With the requirement to create an LED brightness control, the ...

While all of my own devices and monitors don't have PWM dimming for their backlighting, there are some monitors at work which do appear to use PWM. Now many of these monitors are years old, and I ...
