ADI μModule DC-DC — HG drop-in replacements for LTM46xx & LTM80xx

For designs using Analog Devices (ADI / Linear Technology) LTM point-of-load μModule regulators, HGCHIPS offers 30 pin-compatible HG-series alternatives with long-term stock — removing the risk of ADI allocation and premium broker pricing for high-volume or long-lifecycle programs. HG numbering follows the original model digits (e.g. HG4628 ↔ LTM4628 family).
