Description
The LTM4620IY is a dual-channel, high‑efficiency µModule DC‑DC buck regulator from Analog Devices (Linear Technology lineage). It integrates two synchronous buck regulators, their power FETs, control circuitry, an inductor, and most passives into a single compact module, simplifying design and PCB layout. The IY suffix denotes a Pb‑free, RoHS‑compliant package variant.
Key features:
- Wide input range; two independently adjustable outputs with remote sensing, tracking/soft‑start, and sequencing.
- Built‑in protections: overcurrent, over‑temperature, and fault reporting.
- External resistor dividers set output voltages; minimizes BOM and layout complexity.
- High efficiency and fast transient response; suitable for point‑of‑load rails for CPUs, GPUs, FPGAs, ASICs, memory, and telecom gear.
- Very small footprint enables close placement to loads, reducing inductive losses.
For exact specs (input range, current per rail, and package dimensions), refer to the LTM4620IY datasheet and reference design.
