A voltage multiplier is applied as a high source impedance, 36V, 300mA, 12W LED driver. The high source impedance is ideal for driving power LEDs because it accommodates variations in LED junction ...

Diodes Incorporated today announced the release of the AL8806 buck LED driver, capable of producing a constant current of up to 1.5A from voltage sources of between 6V and 30V. Suiting MR16, 12V and ...

The advent of high-power LEDs that can replace incandescent bulbs has produced a need for circuits that efficiently match the LEDs to available power sources (batteries, car electrical systems, etc.).

Fig 1. This voltage regulator circuit (a) uses green LEDs as both the stabilization elements and as the voltage indicators at the front-panel switch (b). Fig 2. The addition of resistor R4 to the ...

Brian Cooley is CNET's Editor at large and has been with the brand since 1995. He currently focuses on electrification of vehicles but also follows the big trends in smart home, digital healthcare, 5G ...

Power Integrations has published a reference design (DER-297) describing a high efficiency, ultra compact driver for a B10 style led light bulb. Based on the company's LinkSwitch-PL non isolated, ...

144 LEDs total. Three sets of 48 in series connected in parallel. My problem is I don't know what value to use for R1. I'm thinking 600 ohm, but I really don't know how to calculate this. I'm making ...

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 ...
