Please help me to identify the IC marked in the picture, the marking states bPDFZ but I couldn't find any relevant information. The board is a TP-Link KC401 home camera.

  • \$\begingroup\$ If you ignore the initial b, the marking seems to line up with the Torex XC6368E. But I'm not sure that's it. \$\endgroup\$

    \$\begingroup\$ @Pxl google search mainly and sometimes lcsc.com, because they have pictures for most parts. In this case I just searched silergy "bPxyz", because I strongly suspected it was a Silergy part from the marking style and context. \$\endgroup\$
