HGCHIPS HG4707 is the pin-to-pin compatible replacement for Analog Devices LTM4707 — the 16V-input, 16A step-down µModule regulator (data sheet Rev. A, Jan 2025) that scales the Silent Switcher 3 architecture to 16A in the same 6.25mm × 6.25mm × 5.07mm BGA, with multiphase current sharing for 32A/48A/64A rails. ADI lists LTM4707 from US$25.04/pc at 1Ku as recommended for new designs; single-unit distributor availability on the newest grade is thin. The HG4707 ships from stock in the identical 49-ball footprint, drops onto the existing LTM4707 layout with no board change, and is bench-verified against the ADI reference profile. Samples available immediately for board validation.

| Official list pricing | Analog Devices lists LTM4707 from US$25.04/pc at 1Ku on the official product page — the highest-current grade of the 6.25mm Silent Switcher 3 family. | analog.com/en/products/ltm4707.html, checked 2026-11-12 |
| Thin retail availability | DigiKey shows the EVAL-LTM4707-AZ evaluation board at US$43.31 with only 24 pcs in stock (tray); Mouser lists the demo board with inventory check — retail stock on the regulator itself is thin for a part this new. | digikey.com / mouser.com EVAL-LTM4707-AZ pages, checked 2026-11-12 |
| Design-in push | ADI application content dated Sep 14, 2026 ("Minimizing Noise in High-Current Applications Using Tiny µModule Regulators") and demo videos (Mar 30 / Jun 26, 2026) target exactly the high-current, noise-sensitive rails LTM4707 serves. | analog.com technical articles & videos, 2026 |
| HGCHIPS supply position | HG4707 samples from stock for board validation; volume pricing at quotation — positioned at parity with ADI 1Ku list for volume commitments; 48h sample shipment. | HGCHIPS price list, Nov 2026 |
Yes — same 49-ball BGA land pattern and pinout; single resistor sets the output voltage and SYNC selects the operating mode, identical to the reference design. It drops onto an existing LTM4707 layout with no board change. Sample evaluation on your board is recommended before production release.
Yes — the part supports multiphase parallel operation with current sharing and CLKOUT synchronization, matching the ADI reference multiphase configurations (2-phase 32A, 3-phase 48A, 4-phase 64A in the data sheet typical applications).
Samples ship within 48 hours. Volume pricing is quoted per BOM line — positioned at parity with the ADI 1Ku list (US$25.04) for volume commitments, well below single-unit distributor pricing on this new grade.
