The Great Search - Compact 3.3V Step-Down with 24V Input and 0.5A output

from Adafruit Industries · host Adafruit Industries

We're wrapping up our WLED board design (https://www.youtube.com/watch?v=M4Ybd8CdQYM) and the last part we need to spec out is the 3.3V regulator. Since we are utilizing USB PD or DC in, we could be running from 5V ~ 24VDC. For the 5V output, we only need a few mA, so we're going to pick the same LDO family we sourced earlier (https://www.youtube.com/watch?v=H_0Kua2UZCs) but for the 3.3V we need at least 500mA of current for the ESP32 chip, so a switching supply is necessary! Let's find something inexpensive with 1A+ output, 24V+ input, and we're also going to need something small so minimal passives and high frequency.
