Abstract
A new low-voltage detecting method for a multichannel LED back lighting unit is proposed. The proposed method detects the lowest voltage drops among the multichannel LED strings with a reduced number of devices, and it provides feedback voltage to control the stages of the boost converter for minimising the power consumption in the LED driving circuit.
