A Novel Integrated Circuit Driver for LED Lighting ()
Abstract
A novel integrated circuit for driving LED lighting has been proposed,
designed and fabricated. Besides the typical parts of LED driver, an integral
part was added at the output terminal of error amplifier in the driver. In this
way, a novel average current mode can be set up to take the place ordinary peak
current control mode. In addition, a BUCK low-level topology was adopted, too. It
can be used to drive up to eight 1 W HB LED lights with 350 mA constant
current. In this way, the LED driver displays high performance, in which output
current with less 1% error and total efficiency as high as 96%. The feasibility
of the design has been verified by actual measurement on the fabricated chip.
