The new driver controls LED luminance using a pulse width modulation (PWM) scheme which gives the application the capability of displaying up to one billion colours. An external resistor is used to ...

In some applications, 16 constant-current sinks may be not enough, but you can easily expand the circuit with additional LED drivers. Only one triple-logic inverter is needed to generate the ...

Comprising eight models, the LDC-185 series of AC/DC LED drivers from MicroPower Direct produces a constant-current output ranging from 0.50 A to 5.25 A at corresponding output voltage levels of 25 ...

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 A6278 from Allegro Microsystems is an 8-channel constant-current latched LED driver incorporating an open LED detection capability. It is a BiCMOS device which includes an 8-bit CMOS shift ...

But do you have any idea how those constant current circuits work? If not, then [Giorgos Lazaridis’] guide on LED driving and controlling methods will bring you up to speed in no time.

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&#… ...

The LED current is adjustable via a high ohmic resistor on a dedicated pin with an IC supply voltage ranging between 6 V and 42 V. For safe and reliable operation and to extend the overall LED ...
