Hello,
I try programing MTP in MPM54304, in datasheet says i need to start up in "safe mode " (page 20).
When i connect external 5V in to EN/SYNC pin, then i apply 12 V to Vin, my converter staring normally, all of 4 converters working properly and produce a nominal voltages. Is not a “safe mode” operation what i do wrong ?
Next i see some MTP topic on forum but i don’t know what is strange registers in I2C like (0x95 of one in topic forum ??).
Bellow is example of my sending formula :
send(0x05,0x2D); // set BUCK2 3V3 → 1V
register 0x05 it’s buck2 config 2D mean 0b00101101 (VREF table it is 1V ) bulked 0 is a multiplayer wich is 1
And it’s working properly.
What i need to do to program MTP (i try once but i bricked my ic them i replace to new one).
Thanks for help
