HG4630A is a pin-to-pin compatible replacement for ADI LTM4630A, a dual 18 A / single 36 A step-down μModule regulator. It matches 4.5 V~18 V input, 0.6 V~8 V output, 36 A single / 18 A dual output and a BGA footprint, so no board redesign is required. Samples start at 10 pcs with lot-level test reports.
Every field below is compared line by line against the original manufacturer's public datasheet before a part is offered as a replacement.

| Input voltage (VIN) | 4.5V~18V | 4.5V~18V | ✔ Same |
| Output voltage (VOUT) | 0.6V~8V | 0.6V~8V | ✔ Same |
| Output current | 36A single / 18A dual | 36A single / 18A dual | ✔ Same |
| Outputs | Dual output | Dual output | ✔ Same |
| Conversion type | Step-down (buck) | Step-down (buck) | ✔ Same |
| Footprint / package | BGA | BGA | ✔ Same |
Compatibility is based on electrical and mechanical comparison against the original manufacturer's public datasheet. Always qualify on your platform before volume use; test reports and application support are provided. LTM4630A is the upgraded version of LTM4630 (better efficiency and thermal performance). HG4630A covers both LTM4630 and LTM4630A; always qualify on your platform before volume use.
When the original is on allocation or past end-of-life, HG parts ship from physical stock — stock lines in 48 hours from Shenzhen.
Every lot ships with traceable validation records for your incoming QA.
Datasheet-level comparison and application support from our Taiwan and Shenzhen engineering team.
Yes. HG4630A is engineered as a pin-to-pin compatible replacement for ADI LTM4630A. Footprint, electrical specification and timing are compared against the original manufacturer's public datasheet, and the part is functionally validated before shipment.
No PCB or firmware change is intended. The part is designed for the same footprint and footprint as ADI LTM4630A. Always qualify the replacement on your own board before volume use — we provide samples from 10 pcs and lot-level test reports for that purpose.
Samples start at 10 pcs. Sample cost is credited against your first production order.
Stock lines ship within 48 hours from Shenzhen. Non-stock and long-lifecycle programs are quoted with a confirmed lead time — send your target quantity and we reply within 24 business hours.
Our Taiwan engineering team compares density, organization, speed grade, voltage, package and temperature grade against the original datasheet, then the part is functionally validated on mainstream platforms, with traceable per-lot records.
Send your target quantity and platform — we confirm compatibility, share test reports and quote within 24 business hours.
