email sent to siliconmitus

who would like to place odds on my getting the info from them?

Mechatrommer:
i bet $1 they will ask your company cert and  sign an NDA and buy 1K lot minimum ;D

    SM4043, SILICON MITUS, MNT, VDD BOOST + VGH BOOST + VGL C/P + VCC BUCK + L/S + OPAMP + DISCHARGING + GPM + PVCOM, QFN, R/TP, 48

and searching for "SILICON MITUS"  reveals that the company does in fact exist and it is Korean: http://www.siliconmitus.com/ --- perhaps try asking them?

Yes mate if you look closer that link to badcaps forum is actually me discussing the problem with this monitor with another member there.  ;)

As you will see if you read through the thread, with the best of our combined efforts the fault has not been resolved yet.  I do have some SM4043 on order from aliexpress but while i'm waiting for them to arrive I thought maybe I would ask here to see if anyone who doesn't read badcaps has a datasheet for this device  ;D

Might be similar to this part but this one is 56 pins so they say...

http://www.siliconmitus.com/main/sub2.asp?avan=1001020000&mcate2=0102000000&pro_title=0102030000&bs_code=pro_list&tbl_product2Mode=products_view01&intseq=101&pro_mcate2=0102030100&RD=SIBDJ0XNN3&

And no pinout in the brief at least.

They might just  be able to get you some kind of information !  Maybe....   Or not...

Or maybe it's more similar to this one which is 48 pins ?

Interesting either way since I had never heard of this company before

Yes it could be something similar to the SM4028 datasheet you linked but that one doesn't have any pin-out or example application circuit either.  Sure it will be similar in function to that one.
