HGCHIPS HG4705 is the pin-to-pin compatible replacement for Analog Devices LTM4705 — the 20V-input, dual 5A (or single 10A stacked) step-down µModule regulator in a 6.25mm × 7.5mm × 3.22mm BGA. Its 3.1V–20V input window covers both 12V and 5V distribution buses, the 0.6V–5.5V output window covers core through I/O rails, and current-mode control with external frequency synchronization and multiphase paralleling makes it the default mid-power PoL for industrial, networking and telecom boards. ADI lists LTM4705 from US$14.03/pc at 1Ku as recommended for new designs. The HG4705 ships from stock in the identical footprint, drops onto the existing LTM4705 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 LTM4705 from US$14.03/pc at 1Ku on the official product page — one of the cheapest complete 20V µModule solutions ADI offers. | analog.com/en/products/ltm4705.html, checked 2026-11-13 |
| Franchised stock thin | Catalog checks on 2026-11-13 show franchised distributors surfacing mainly the DC3051A demonstration board for this grade rather than tube/tray IC stock — the IC itself is moving through contract channels. | digikey.com / mouser.com LTM4705 catalog check, checked 2026-11-13 |
| Mature, active grade | Launch coverage dates to Jul 2022 (All About Circuits product brief) and ADI still marks the part recommended for new designs — a stable, high-volume 12V-bus PoL that suits a second-source strategy. | allaboutcircuits.com new product brief 2022-07-19; analog.com status, checked 2026-11-13 |
| HGCHIPS supply position | HG4705 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 6.25mm × 7.5mm BGA land pattern and pinout, same single-resistor output setting, tracking/soft-start and Burst Mode behavior. It drops onto an existing LTM4705 layout with no board change. Sample evaluation on your board is recommended before production release.
Yes — both channels can be combined for a single 10A output, and multiple parts can be paralleled in multiphase with current sharing and external frequency synchronization, matching the ADI reference configurations.
Samples ship within 48 hours. Volume pricing is quoted per BOM line — positioned at parity with the ADI 1Ku list (US$14.03) for volume commitments, well below single-unit distributor pricing where available.
