I have a Chinese made device (let's keep the mystery for a tiny bit) that runs on a lithium-ion battery with 13 cells.
With a fully charged battery where each cell is at 4.2V that would result in 54.6V at VIN.
VOUT if my math is right would be 15V. That means a 39.6V drop.
But before we go further into the merits of this circuit, what is the purpose of R62?
