HGCHIPS supplies 21 pin-compatible replacements covering the LTM46xx family of ADI μModule point-of-load DC-DC regulators. Each replacement is compared against the original datasheet — footprint, pin-out, input and output voltage range, output current and package — and validated against the original datasheet with per-lot records.

Guides: the 7 checks before a µModule drop-in switch · how to qualify an alternative part.
HGCHIPS supplies 21 pin-compatible replacements covering the ADI LTM46xx μModule family. Every module is compared against the original datasheet — footprint, pin-out, input and output voltage range, output current and package.
No board redesign is intended. The modules share the original LGA / BGA land pattern, so the intent is a drop-in swap. Always qualify on your own board before volume use — we provide samples from 10 pcs and lot-level test reports.
Samples start at 10 pcs, with sample cost credited against your first production order.
The main driver is supply certainty: ADI allocation and premium broker pricing on long-lead parts, versus a long-term stock commitment on our side.
We confirm compatibility, share test reports and quote within 24 business hours — samples from 10 pcs.
