LTM4662IY#PBF

LTM4662IY#PBF is a dual high-efficiency µModule DC-DC regulator from Analog Devices (Linear Technology lineage). It integrates the power stage (MOSFETs), control circuitry, and often the inductor into a single compact package, delivering two low‑voltage rails from a higher input voltage for heavy digital loads (CPUs, FPGAs, memory, etc.). Key points:
- Two independently regulated outputs (VOUT1, VOUT2) with programmable or fixed voltages.
- Wide input range and high efficiency for dense power delivery.
- Built‑in protection: overcurrent/short‑circuit protection, thermal shutdown, undervoltage lockout, and soft‑start.
- Easy board integration: minimal external components beyond decoupling capacitors and feedback resistors; often supports remote sensing.
- Good for space‑constrained applications requiring multiple rails, reduced BOM, and quick time‑to‑market.
Suffix notes:
- #PBF denotes Pb‑free (RoHS) packaging.
- IY is the specific package/temperature grade code.
For exact electrical specs, pinout, layout guidelines, and programming options, refer to the LTM4662IY#PBF datasheet.
