The Great Search: Boost converter OLED bias / FAN5331 replacement #TheGreatSearch #digikey @DigiKey @Adafruit

(Video) A few months ago, we were forced to find a replacement for the FAN5333 constant-current LED driver. Well, now we have to find a replacement for its sister – the fixed voltage boost converter FAN5331 which has gone “end of life” on us.

A real tragedy: we absolutely loved this simple SOT-23-5 chip which could take 3-5VDC in and give up to 20V out with a built in 1A switch, only a small inductor and diode needed! We use this for many of our OLED displays and other devices that need a bias voltage of 12-18VDC. Let’s see if we can locate a pin-compatible, functionally-similar equivalent that’s in stock.
