📋 Design-in verification checklist

  • Footprint / pin-out vs. the original LTM module
  • Input & output voltage / current range match
  • Switching frequency & loop stability on your load
  • Thermal performance in your layout
  • Output ripple / noise measurement

HGCHIPS provides datasheets, test reports and application support for every HG model.

💡 Why switch to HG

  • Price stability vs. ADI allocation & broker premiums
  • Long-term availability commitment for your program
  • Technical support from Taiwan + China application engineers
  • Samples from 10 pcs — qualify before you commit

Frequently asked questions about ADI µModule replacement

Which ADI modules do you replace?

LTM46xx (21 part numbers) and LTM80xx (8 part numbers), mapped to HGCHIPS equivalents named HG46xx and HG80xx. Send the exact LTM part number and we confirm the match.

Do you also supply original ADI stock?

Yes. Original ADI stock, for example LTM3605, is supplied as the original part, not as a replacement.

How is compatibility confirmed for a power module?

Per original part number: we confirm the pin-out, the package and the electrical comparison, and quote the matching HGCHIPS part.
