Hello,

I have a -12v regulator converter with P/N PT78NR112V and it contains an 8-Soic IC with p/n markings "105085".

Does anyone know where I can get a datasheet for this component?

I've looked just about everywhere I can think of and seems like no one has it.

Thank you for your time,

Hugo

Hi Sandesh:

The recommended replacement for buck boost PT78NR112V is the PTN78000AAH

PTN78000AAH is electrically similar toPT78NR112V with maximum 9W, 12Vout at 0.75A. It is not mechanically equivalent.which will require a PCB layout .
