Practical LED driver circuit. With the feasibility demonstrated, I designed the previous voltage multiplier LED driver. The output current may be scaled simply via adjusting the capacitor values. All ...

1. A linear-current-source LED driver works best in low-power applications. Basic LED Driver Topologies. Modern LED driver circuits resemble a switch-mode regulator or dc-dc converter.

The 2-MHz, dual 1-A (or more) buck LED driver demonstration circuit DC2424A features a high-efficiency, compact layout. It can be altered to power up to 30 V of LEDs per channel from a 34- to 36-V ...

When LEDs from various bins are used, the designs of LED lamps must accommodate a wide range of forward voltage. Therefore, each LED driver will be a 350 mA current source designed to work from an ...

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. Dubbed DER-322, the circuit is desigend to fit neat ...

The whole thing was mounted in a full-brim hard hat with 1W “high-beam” and 3 “low-beam” LEDs; an 12 red warning LEDs around the rim driven by two more 74HC14 circuits (one as a pierce ...

A poor-quality LED bulb isn't the only thing that can cause the glow. If you're using switches with motion sensors or timers, the LED bulb may draw power from their circuits and emit a faint glow.
