At 2 MHz the switching edges are fast enough that a few nH of stray inductance in the input loop will produce visible ringing on the switch node. Keep the input decoupling capacitors within 2–3 mm of the BGA ball-out, and use a solid ground plane on layer 2.
It is ROHS3 compliant (lead-free, no exemptions). For a new-design BOM this is a clean qualification target; no supply-chain clock is ticking.
No. It is suitable for new designs.
The LT8643SHV-2#PBF (single-output Silent Switcher 2, 6 A, 2.1 MHz, -40°C to 150°C) and the ADP2166ACPZ-R7 (single-output, 6 A, 1.4 MHz) are both single-channel buck regulators from the same supplier ecosystem. Neither is a drop-in replacement — the LTC3376EY#PBF is chosen specifically for its quad-output capability in a single BGA. If you only need one rail, a single-output part saves board area and BOM cost.
There is no exact replacement. The LTC3376EY#PBF is an active, current-production part from Analog Devices. No successor or second-source alternate is published. If you need a quad-output buck regulator in a similar footprint, the LTC3376EY#PBF is the part.
