Why does a boost converter need 11 mA without a load?
I use a FP6296XR-G1 (U10 / 10A boost converter) together with a MBR20100CS (D5 / dual Schottky diode in a TO252-2 package) in order to make 13 V out of 2.5-5 V.
When I connect BOOin to 5 V from an ...

ESP32 with two power supplies (AC/DC + USB) using Schottky diodes
I'm building a small circuit to power an ESP32 with two different power supplies.
Normally the circuit will be powered from AC, using a Mean Well IRM-02-5 AC-DC power supply to get 5VDC out of 220VAC.
