Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

A common method for drivingmultiple power LEDs is throughtwo parallel strings. This inexpensiveand less critical driver circuit can providea lower voltage. However, the driver circuitmust deliver ...

This custom circuit board picks up some of the pieces from a wall wart to drive a high-power LED. The basic concept is to keep the high-voltage components and swap out the low voltage ones for parts ...

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. An LED-driver reference design for an LED replacement ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

Fig 1. Single 1-W LEDs can serve as high-power, high-brightness devices. Fig 2. Certain LED applications fall into a gray area where low-power and high-power components both can fit the bill. However, ...

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 ...

ANSAN, South Korea--(BUSINESS WIRE)--Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a leading global innovator of LED products and technology, announced that it has introduced high-power LED package ...
