Our latest article has been published in EDN Europe and covers the design of RD005, our reference design which drives three Luxeon K2 LEDs from a Power over Ethernet connection.

RD005 Reference Design LED Drive Stage

RD005 uses a peak current PWM switching scheme to control the LED current. This provides a simple low cost control mechansim which gives excellent conversion efficiency. The full report engineering report for RD005 can be found in our reference design library.
