In Part 1 of this two-part series, “Creating Uniform LED Luminescence in RGB Displays”, the discussion focused on dot correction. This design technique is used for managing individual pixel brightness ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

However LEDs are dimmed – be it by 1 – 10 V analogue voltage, mains phase angle, power-line, digital inputs such as DALI, or a WLAN link, there is in fact only two ways to actually dim the output of a ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

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 ...

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 ...

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.

Have you ever looked at your phone and gotten a headache? Sometimes, it just means you've been on it too long and need to take a break. For some folks like me, it's the display itself that's causing ...
