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

According to the SEAD (Super-efficient Equipment and Appliance Deployment) initiative, televisions are responsible for approximately 3 to 8% of global residential electricity consumption. An analysis ...

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 ...

The Extreme High Power (XHP) LEDs are a new class of LEDs that can reduce system costs by up to 40% in most lighting applications. The first available family member is the XLamp XHP50 LED, delivering ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

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 ...

I have a Vinsic VSPB304 powerbank which has three outputs - two USB-A (rated at 2.4A each) and one USB-C (rated at 3A). All three can be used at once but the maximum combined output is 5A. I want to ...

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

Researchers at Ben-Gurion University of the Negev have demonstrated a novel way to spy on electronic conversations. A new paper released today outlines a novel passive form of the TEMPEST attack ...
