This project is a simple universal Power LED Driver. The Power LED can be controlled by the built-in PWM signal generator or driven from an external drive signal depending on how the hardware is ...

The LM3463 by Texas Instruments is a six-channel LED driver with dynamic headroom control for high-power applications that accurately drives up to six strings of LEDs. The biggest cost reductions in ...

Last week, Zetex released three power LED driver chips. Electronics Weekly decided to look deeper into the technology. There are three white power LED drivers; the ZXLD1320 1.5A buck, 1321 1A boost ...

Maxim Integrated Products’ MAX16806 is an EEPROM-programmable, 350-mA, high-voltage (40-V) linear, high-brightness LED driver. This IC can be programmed through an I 2 C interface to fold back the LED ...

Opto-electronic systems frequently require temperature stabilization for components such as laser diodes, photodiodes, prisms, and lenses. The established method for providing stabilization is to ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

Guest columnist Jeff Gruetter, product marketing engineer for power products at Linear Technology outlines why high brightness LEDs require high performance LED drivers High brightness (HB) white LEDs ...

Woburn, MA — Innovations in Optics, Inc. introduces the Model 5000A-100 LED driver/controller for powering its patented and patent-pending high power LED light engines. The 5000A-100 LED driver ...

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 ...

[Maximilian Güntner] dropped us a comment in last week’s globe writeup linking to his own project, which involves a similar high power LED driver mod. This looks like the exact same mod we came up ...
