概述
Description
LTM4655IY#PBF is Analog Devices’ Linear Technology LTM-series multi-output DC-DC buck regulator. The IY suffix denotes a specific Pb-free package variant, and #PBF confirms Pb-free (Pb-F) packaging.
Key idea:
- It combines a controller and power MOSFETs for multiple low-voltage outputs in one package, with a PMBus-compatible digital control/monitoring interface.
- Used to generate several rails from a higher input in systems like CPUs/GPUs, servers, and telecom gear.
- Features typically include programmable output voltages, remote sensing, protection (OC/OV/OP/thermal), fault reporting, and efficient regulation.
What to do next:
- See the LTM4655 datasheet and application notes on Analog Devices’ website for exact pinout, electrical specs, and reference designs.
- Check the evaluation board (LTM4655EVAL) for practical implementation guidance.
Note: IY is the package code; PBF indicates Pb-free.
