This is a boost converter powered LED board. It’s intended to be populated with 21 SM0603UV-405 UV LEDs, but really any 0603 LED would work just fine. The boost converter is the AP3015. The two 1210 caps are 10 µF, the inductor is 10 µH and the diode is an MBRA340 Schottky diode. The resistor divider values of 51.1kΩ and 3kΩ yield an output voltage of 22.14 volts, or 3.16 volts across each LED (there are 3 parallel strings of 7 LEDs in series). It’s recommended that the input power be 9 VDC.
