LED driver with single inverter circuit with isolated multi-channel outputs

A single-converter circuit-based LED driver circuit with isolated multi-channel outputs is disclosed. The circuit includes an IC control circuit, a plurality of isolated output channels each having an output current sensing and conditioning circuit, and an output current regulation circuit. The output current regulation circuit includes a voltage-sensing transformer winding (T) that senses an output voltage level across a secondary side of the circuit, and a peak output current sensing component that senses output currents from the isolated output channels and determines which channel has a highest current output. Additionally, the circuit facilitates providing output current regulation when detected output voltage is below a predetermined threshold, and providing output current regulation when the detected output voltage is above the predetermined threshold.
