The HV9803 is a LED driver IC with average-mode constant current control and operates in a constant off-time mode. It can be powered from a 7.0 – 13.2 V supply. The device is equipped with a current ...

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 ...

A constant current is better than a constant voltage for driving LEDs. In this proposed circuit, a common constant-voltage regulator is changed into a constant-current source for LEDs. In addition, a ...

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 a slew ...

Diodes Incorporated's AL5809, offered in a robust two-terminal PowerDI®-123 package, provides an improved accuracy, cost-effective solution for constant-current linear driving of LEDs. With its 1.2W ...

Typical uses today include backlighting for LCD TVs, projectors, computer displays, camera flashes, and vehicle brake lights. All need constant-current LED drivers that are economical and offer high ...

Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...

Linear Technology has introduced a synchronous step-down DC-DC converter which will deliver a 20A current to drive high current LEDs. The LT3743 will drive up to 20A of continuous LED current from a ...
