  • Driving high-power LEDs in series-parallel arrays
  • Strange. The conclusion is basic series parallel can't be done but we regularly used series parallel LED backlights in LCD character modules in the 90s. Even for 4x40 modules with 4 parallel rows of maybe 20 LEDs/row. Am I missing something?
