HGCHIPS HG4712 is the pin-to-pin compatible replacement for Analog Devices LTM4712 — the four-switch, high-current buck-boost µModule regulator that holds a 5V–36V input and 1V–36V output window in a single 16mm × 16mm × 8.34mm BGA. Because it regulates seamlessly whether VIN sits above, below or across VOUT — 12A in buck and buck-boost mode, up to 98% efficiency, parallelable for higher current, with input/output average current limit and monitoring for battery-charging and LED duty — it is the default wide-input power stage for industrial, battery-powered and telecom equipment. ADI lists LTM4712 from US$42.76/pc at 1Ku and still marks it recommended for new designs. The HG4712 ships from stock in the identical land pattern, drops onto the existing LTM4712 layout with no board change, and is bench-verified against the ADI reference profile. Samples available immediately for board validation.

Yes — same 16mm × 16mm BGA land pattern and pinout, same peak-current-mode control model, frequency lock range and Power Good behavior. It drops onto an existing LTM4712 layout with no board change. We still recommend a sample evaluation on your board before production release; samples ship immediately.
Yes — that is the core of the four-switch buck-boost topology: seamless regulation across the pass-through region, plus adjustable input/output average current limits and current monitoring for battery-charging duty, matching the ADI reference configurations.
HG4712 matches the ADI scheme: cycle-by-cycle peak current mode, programmable average current limit on input or output, and current-sharing paralleling for higher output power. The evaluation comparison report is available under NDA.
