Here is the most probable answer to the devices marked "05" www.eevblog.com/forum/repair/sot23-6-with-marking-code-05-or-o5/msg4688066/

UPDATE: I am pleased to report that after replacing the device marked AWHM with an MP1567GTF chip (marked AWHN, so 2021 production year) the camera is FULLY OPERATIONAL (unlike Darth Vader's Death Star) I bought the chip here: www.aliexpress.com/item/1005004217646276.html

A perfectly reasonable conjecture @VorlonFrog . After all, there is another linear regulator proximate to an SMPS on this PCBA. However, the fingerprint is not a match. SOT23 Linears are typically 3 pin or 5 pin. I had also thought similarly when I cam across them. Incidentally the two...

Thank-you very much @VorlonFrog Also these: smd.yooneed.one embedeo.org/smd_codes www.random-science-tools.com/electronics/SMD_markings.php www.marsport.org.uk/smd/mainframe.htm www.formatecauto.com/wp-content/uploads/2015/03/tabela-de-equivalencias-transistores-1-EFREN.pdf And I notice...

I just tore down a Reolink RLC-510WA WiFi CAM since one of the 5 buck switching power supplies on the main PCBA was in need of repair. Yes there are FIVE 5! SMPS on the main PCBA of RLC510WA and two LINEAR regulators. But I digress. Can anyone help me identify the SMPS controller chip in the...
