Présentation
Description
LTM4649EY#PBF is a compact, fully integrated µModule buck regulator from Analog Devices (formerly Linear Technology). It consolidates switching regulators, power MOSFETs, inductors, and control circuitry into a single module and provides multiple regulated rails for high‑current digital loads (CPU cores, FPGAs, memory, etc.). The device offers a PMBus digital interface for voltage programming, sequencing, telemetry, and fault protection, simplifying system design and BOM. The EY suffix denotes a specific packaging variant, and #PBF indicates a Pb-free, RoHS-compliant part. Typical use cases include servers, telecoms, and embedded compute platforms where fast time‑to‑market and reliable multi‑Rail power are required. For exact input ranges, output voltages, current capabilities, and pinout, consult the LTM4649 datasheet and product pages.
Features
Key features of LTM4649EY#PBF (µModule regulator):
- Dual synchronous buck regulator in a single µModule with PMBus/I2C control.
- Wide input voltage range (typical 4.5V–60V) with undervoltage protection.
- Two independently configurable outputs with sequencing and soft-start.
- Remote sense and accurate output regulation for load transients.
- Programmable via PMBus/SMBus (setpoints, readbacks, status/fault reporting).
- Robust protection: overcurrent/short-circuit limits, overvoltage protection, thermal shutdown.
- High efficiency and compact power density; minimal external components (feedback resistors only).
- Fault reporting and power-good signals; status indicators.
- Wide operating temperature (industrial to extended) suitable for harsh environments.
- Includes integrated inductor, drivers, and MOSFETs (no external power stages required).
Note: For exact voltage ranges, current limits, sequencing details, and pinout, please refer to the latest datasheet for the EY#PBF package variant.
