# ADI LTM4710-1 Compatible Replacement — HGCHIPS HG4710-1 Low VIN, Quad 8A Silent Switcher µModule

> HGCHIPS HG4710-1 is the pin-to-pin compatible replacement for Analog Devices LTM4710-1 — the low-VIN, quad-output step-down µModule regulator that puts four independently configurable 8A Silent Switcher 2 rails in a single 6mm × 12mm × 3.54mm LGA, CISPR32 Class B compliant out of the box. It is the part AI accelerator, FPGA and optical-module designers reach for when one small package must generate 0.5V–3.6V core, I/O and transceiver rails from a 2.5V–5.5V intermediate bus. ADI lists LTM4710-1 from US$39.54/pc at 1Ku as recommended for new designs, while franchised-distributor stock on the IC itself is down to single digits. The HG4710-1 ships from stock in the identical land pattern, drops onto the existing LTM4710-1 layout with no board change, and is bench-verified against the ADI reference profile. Samples available immediately for board validation.

| Signal | Detail | Source |
| --- | --- | --- |
| Official list pricing | Analog Devices lists LTM4710-1 from US$39.54/pc at 1Ku on the official product page — quad 8A density at roughly twice the price of a single-rail 12A grade reflects its multi-rail silicon content. | analog.com/en/products/ltm4710-1.html, checked 2026-11-13 |
| Single-digit franchised stock | DigiKey (CA) shows LTM4710IV-1#PBF with only 1 pc in stock at CA$159.19; DigiKey (US) has the DC3164A-B evaluation board at US$67.70 with 1 pc — design-win demand on this grade is real and the channel is thin. | digikey.com / digikey.ca LTM4710-1 listings, checked 2026-11-13 |
| Application pull | The 0.5V–3.6V output window and 1MHz–5MHz programmability target exactly the rails AI accelerators, FPGAs and 800G optical modules need from a 3.3V/5V intermediate bus — the fastest-growing PoL segment of 2026. | analog.com LTM4710-1 product positioning, checked 2026-11-13 |

## FAQ

**Q: Is HG4710-1 a drop-in replacement for LTM4710-1?**

Yes — same 6mm × 12mm LGA land pattern, pinout and programming model (frequency select, per-channel output set, Power Good and die-temp monitoring). It drops onto an existing LTM4710-1 layout with no board change. We still recommend a sample evaluation on your board before production release; samples ship immediately.

**Q: How does HG4710-1 compare on noise and EMI?**

The HG4710-1 is bench-verified against the ADI reference profile, including the Silent Switcher 2 noise signature and CISPR32 Class B radiated emissions. The evaluation comparison report is available under NDA.

**Q: What about temperature grades and the IV suffix?**

The reference LTM4710IV-1#PBF is the industrial-temperature grade. Tell us your exact BOM line (including any automotive or military screening) and we confirm the matching HG4710-1 grade in writing before you commit.
