This paper presents a two-stage multichannel light-emitting diode (LED) driver, which contains a buck converter as the first stage and a multichannel constant current CLL resonant converter as the second stage. The forward current of one LED string is sensed for feedback control to regulate the bus voltage, which is the input voltage of the CLL resonant converter. Meanwhile, the currents of other...
This paper proposes a two-stage multi-channel LED driver, which contains a buck converter as the first stage and a multi-channel constant current (MC3) CLL resonant converter as the second stage. The forward current of one specific LED string is sensed for feedback control to regulate the bus voltage, which is also the input voltage of the MC3 CLL resonant converter. In contrast, the MC3 CLL is unregulated...
