Likely a custom or proprietary integrated circuit (IC) — common in power management, LED driver, or DC-DC converter applications, often found in compact modules.
Typically available in a small surface-mount package such as SOT-23-6 , SOP-8 , or DFN .
Here’s a proper write-up for , formatted for clarity and professionalism depending on your context (e.g., datasheet reference, inventory label, or schematic note). Component / Part Number: AC8667L
Not a standard industry-wide part number (e.g., not from TI, ON Semi, or Analog Devices). Likely from a Chinese or secondary semiconductor supplier. Refer to the original manufacturer's datasheet for absolute electrical characteristics.
Standard ESD precautions required. Verify pinout with PCB layout before soldering. If you need me to tailor this write-up for a specific use case (e.g., repair log, BOM, or product documentation), let me know.
