LED DRIVER WITH SINGLE INVERTER CIRCUIT WITH ISOLATED MULTI-CHANNEL OUTPUTS
A single-converter circuit--based LED driver circuit (10) with isolated multi-channel outputs is disclosed. The cir-cuit (10) includes an IC control circuit (11), a plurality of isolated output channels (70, 74) each having an output current sensing and conditioning circuit (74, 90), and an output current regulation circuit (128). The out-put current regulation circuit (128) includes a voltage-sensing transformer winding (T4) that senses an output voltage level across a secondary side of the circuit (10), and a peak output current sensing component (156) that senses output currents from the isolated out-put channels and determines which channel has a highest current output. Additionally, the circuit (10) facilitates providing output current regulation when detected output volt-age is below a predetermined threshold, and providing output current regulation when the detected output voltage is above the prede-termined threshold.
