The Great Search - White LED strand backlight constant current driver (FAN5333 replacement)

Adafruit Industries

Another day, another part we can't get! This week we're on the hunt for a replacement for the FAN5333 (https://www.digikey.com/short/bc3jrj8w), a constant-current, 24V boost converter that we use for our TFT displays with big back lights like the 4.3" touchscreen (https://www.adafruit.com/product/1591). These displays often have 6 or 7 white LEDs in series, and sometimes multiple strands of them! That means boosting 3.3V or 5V up to 22VDC with 50 to 100mA of current. That's a lot of power! Let's find a good alternative at Digi-Key so we can keep making display breakouts that folks love - ideally one that is drop-in compatible with the FAN5333 or at least one with minimal design changes required.
