LTM8065EY#PBF

Introduction to LTM8065EY#PBF
- What it is: A fully integrated µModule DC-DC buck regulator from Analog Devices (Linear Technology lineage). It combines the controller, MOSFETs, inductor and support circuitry in a compact module to generate a regulated output from a higher input.
- Key features: wide input range, adjustable output via external feedback, high efficiency, fast transient response, and protection features (overcurrent/short-circuit, thermal shutdown, undervoltage lockout). Designed for point‑of‑load use in automotive/industrial apps.
- Package/marking: EY denotes a specific mechanical variant; #PBF indicates Pb‑free, tape‑and‑reel packaging.
- When to use: to achieve a compact, low‑BOM, high‑efficiency supply with minimal external parts.
- How to design: connect Vin and GND, set Vout with the feedback network per the datasheet, add required input/output capacitors, and ensure proper thermal management.
- Learn more: consult the LTM8065 datasheet and Analog Devices product pages for exact electrical specs, pinout, and application notes.

There is no single exact third‑party drop‑in equivalent for the LTM8065EY#PBF. Use other LTM8065 family variants from Analog Devices (same µModule) or, after validating specs/footprint, consider functionally similar μModule/regulator substitutes such as TI’s LMZM23600, Murata OKI‑78 series, or RECOM R‑78 series. Confirm electrical, thermal and mechanical compatibility before replacing.

Here are the key features of the LTM8065EY#PBF:
- Fully integrated µModule buck regulator (no external magnetics required)
- Input voltage range: 4.5V to 36V
- Output current: up to 6A continuous
- Output voltage: adjustable 0.8V to 5.0V (remote sense and trim available)
- High efficiency (typical up to ~95%)
- Internal inductor, MOSFETs, and controller
- Remote sense and output voltage trim for accurate regulation
- Enable/shutdown control with soft-start
- Protections: overcurrent/short-circuit, overvoltage, thermal shutdown, current limit
- Operating temperature: -40°C to 125°C (industrial/automotive suitability)
- Package: Pb-free, RoHS-compliant LTM8065EY#PBF µModule
Applications include telecom, industrial, and automotive power rails where a compact, efficient, wide-input regulator is needed. For exact electrical specs and pinout, please refer to the datasheet.

Pin count: 16 pins (in a µModule/LGA package).
Function: LTM8065EY#PBF is a fully integrated buck regulator µModule. It contains the switching regulator, control circuitry, and inductive energy storage in one package and converts Vin to a regulated Vout. Pins provide Vin, GND, Vout, feedback (FB) for regulation, enable (EN), and status/control signals (e.g., power-good), with any remaining pins as non‑connect. It includes protection features such as overcurrent/overvoltage and soft-start.

Manufacturer: Linear Technology Corporation (LTC), now part of Analog Devices.
Type of company: a semiconductor firm specializing in high-performance analog and mixed-signal ICs—particularly power-management solutions (voltage regulators, µModule power modules), data converters, amplifiers and related analog components.

Common application areas for LTM8065EY#PBF:
- Automotive electrical systems (wide Vin, transient-tolerant power rails)
- Industrial automation and motor-control power supplies
- Telecom and datacom equipment needing compact VRMs
- Embedded computing platforms (FPGAs, ASICs, SoCs) as a point-of-load regulator
- Space-constrained or rugged power-supply applications requiring high efficiency and an integrated module
