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 ...
