LTM8025EY#PBF

LTM8025EY#PBF is Analog Devices’ LTM µModule buck regulator. It’s a highly integrated DC-DC converter that combines a switching regulator, power MOSFETs and inductor inside a single miniature module, so you add only input/output capacitors and a feedback network.
Key points
- Wide input range: supports a broad Vin (typical 4.5–60 V).
- Output: adjustable via feedback resistors (and suitable for common rails; respect datasheet for exact range).
- Efficiency and speed: high efficiency with fast transient response for compact designs.
- Protections: overcurrent/short-circuit protection, overvoltage protection, thermal shutdown, and soft-start.
- Features: often includes remote sense and sequencing options, depending on the exact variant.
- Package: EY µModule package; PBF denotes RoHS/lead-free version.
Typical use
- Automotive, telecom, industrial and embedded power rails where a compact, easy-to-design regulator is needed.
Note
- Exact output voltage, current rating, and pinout vary by variant. Check the LTM8025 datasheet and the “EY”/“PBF” notes for precise specs and application circuits.

Key features of LTM8025EY#PBF:
- Fully integrated µModule regulator (controller, power MOSFETs, inductor, and most passives) in a compact package
- Wide input voltage range suitable for automotive/battery applications
- Output voltage adjustable via external resistor network; suitable for common rails (e.g., 1.x–5.x V ranges)
- High efficiency with fixed-frequency synchronous switching
- Enable input and Power-Good signaling; optional remote sense and soft-start
- Robust protection: input UVLO/OVLO, output overcurrent/short-circuit, overtemperature with thermal shutdown
- Current limit protection and safe-start behavior
- RoHS-compliant, lead-free (PBF) and 100% tested
Note: exact numeric limits (input range, output range, current capability) are specified in the datasheet; verify for your design.

LTM8025EY#PBF is supplied in Analog Devices’ µModule (LGA) package. The “#PBF” suffix indicates a RoHS-compliant, Pb‑free (lead‑free) finish.

- Pin count: 16 pins (16‑pin LGA package).
- Function: A μModule DC‑DC buck regulator; integrates the switching regulator circuitry (controller and power MOSFETs) to convert a higher input voltage to a regulated lower output, with onboard feedback/enable features.
