Love tomb style No. 307 - high voltage 80V to 48V_TX4131L

Overview

The default design is 80V to 48V

In fact, the MOS withstand voltage is 100V, while the IC can work under 150V input

Therefore, it is recommended that the input be between 60-80V (as for the input MIN voltage, it depends on actual testing)

Output current maximum 10A

The inductance theory requires 369UH, I think it has been verified

All input and output use XT30

The circuit is BUCK non-synchronous rectification (so the heat is huge) and the output is within 5A.
