This paper presents an LED driver circuit consistingof a voltage pre-regulator and multiple linear current regulatorswith an adaptively-controlled supply voltage. The proposed
driver circuit powers all LEDs in a string with a constant currentand provides consistent illumination and optimal operatingefficiency at low cost. The performance of the proposed driverwas verified experimentally.
