Here is a look back of Allegro’s A8515, a wide input voltage range, high efficiency fault tolerant white LED driver. The device was made available in the market since 2010. It features multiple output ...

This article is excerpted from Section 21 of “Analog Circuit Design: Volume 3 – The Design Note Collection,” (ISBN: 978-0-12-800001-4), edited by Bob Dobkin and John Hamburger of Linear Technology ...

A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...

Texas Instruments Incorporated introduced a six-channel LED driver with dynamic headroom control for high-power applications, which accurately and efficiently drives up to six strings of LEDs. Texas ...

High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.

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 ...

Toshiba has a voltage driven photo relay with a tiny S-VSON4T package and reduced input power dissipation. The TLP3407SR, features a maximum LED current of just 1 mA at the input, which represents a ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...
