Abstract

LED DRIVER, SYSTEM, AND METHOD FOR CONTROLLING LED DRIVER ABSTRACT The present disclosure generally relates to a LED driver, a system comprising the same, and a method for controlling the same. The LED driver comprises: an input port; a plurality of output ports, each output port being configured to be electrically connected to at least one LED; a switched power converter including a plurality of converter branches, each converter branch being electrically connected between the input port and a respective output port among the plurality of output ports and comprising a switch for power conversion; and a control unit configured to control the plurality of converter branches in an interleaved manner, the switch of each converter branch being switched on for a corresponding on-time interval within an interleaving period and switched off for a remainder of the interleaving period, wherein the control unit is configured to control the on-time intervals corresponding to the plurality of converter branches such that at least one converter branch has a corresponding on-time interval that is different from at least one other converter branch.
