Date Announced: 07 Feb 2012 Sunnyvale, CA – Supertex, Inc. (Nasdaq GS: SUPX) today introduced HV9989, a three channel, boost LED driver integrated circuit (IC) designed to drive LEDs in LCD ...

Today’s drivers with two or more independent LEDs (ILEDs) can control a portable system’s fun light (multiple light sequences with several colored LEDs to make a phone, say, more attractive to a user) ...

Linear Technology Corp. introduces the LT3761, a dc/dc controller designed to operate as a constant-current source and constant-voltage regulator. It also features a programmable internal PWM dimming ...

Lots of modern phones use pulse width modulation, or PWM, to manage brightness. But what is PWM, why is it harmful, and what can you do about it? We give you all the details.

Linear Technology Corporation has announced the LT3496, a 2MHz DC/DC converter designed to operate as a three-channel constant current LED driver. Each of the LT3496’s three channels can drive up to ...

A pair of dimmable, ac-dc digital pulse-width modulation (PWM) controllers for 100-V/230-V ac offline LED lighting applications illustrates the design complexity of what at first glance seems a simple ...

Diodes has launched a boost/single-ended primary inductance converter (SEPIC) controller for various automotive LED applications. The AL8853AQ is an automotive-compliant and highly integrated ...

I'm trying to dim LED strips, approximately 30ft in length, with hand controls. I've found that regular potentiometers (those sold by Adafruit) max out at about 0.2 W. For whatever reason, the Red ...

The LT3796-1 is a switching controller designed to regulate a constant current or constant voltage at the output—necessary requirements for driving LEDs. It uniquely features two independent current ...

To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller.
