Since the module handles mains voltage, the heatsink and PCB should be treated as "live." If mounted to a metal panel, ensure the panel is properly grounded. Interference: The 9892 series typically refers to one of

  1. Identify the full manufacturer prefix – Is it LM9892, RT9892, MP9892, or TPS9892? The prefix changes the datasheet.
  2. Use parametric search – Go to Mouser, DigiKey, or Octopart. Enter “9892” and filter by “datasheet available.”
  3. Check manufacturer websites – Texas Instruments, Analog Devices, Monolithic Power Systems, or Richtek.
  4. Look for “marking information” – In the datasheet, search for “top marking” or “package marking diagram.”
  5. Verify revision – Ensure you have the latest revision (e.g., Rev C vs. Rev A). Older revisions may have errors in the top specs.
