Présentation
Description
The LTM4646EY#PBF is a high‑density, multi‑output buck regulator in a μModule (micro‑module) package from Analog Devices (Linear Technology). It combines multiple switching regulators, control logic, protection, and optional PMBus/I2C control in one compact module to generate several rails from a single input.
Key points:
- Multi‑output, digitally programmable power module
- PMBus/I2C interface for voltage programming, sequencing, margining, and fault monitoring
- Built‑in protections (overcurrent, over/under voltage, thermal, fault/power‑good signaling)
- Remote sensing, output tracking, and configurable sequencing for complex power rails
- High efficiency and fast transient response in a small form factor
Typical uses include CPU/GPU/FPGA core and memory rails, ASICs, and other multi‑rail digital systems.
Packaging: EY#PBF indicates a specific lead‑free, RoHS‑compliant variant in the LTM4646EY package. For exact rail counts, voltages, input range, and programming, consult the LTM4646 datasheet.

Features
LTM4646EY#PBF features (concise):
- Six integrated synchronous buck regulators in a single µModule package (multi-rail power solution).
- PMBus interface for digital control, monitoring, and fault reporting; VOUT, IOUT, temp readback and status flags.
- Programmable per-channel output voltages with sequencing/margining and remote sensing.
- Wide input voltage range (typical 4.5V–60V) with high overall efficiency.
- Integrated power components (inductor and passives) in a compact package; no external inductors required.
- Robust protection: OVP, UVLO, over-current/short-circuit protection, over-temperature with latch.
- Remote sense capability, automatic current limiting, soft-start and output discharge on shutdown.
- Telemetry and fault signaling via PMBus; fault latch and configurable limits.
- Operating temperature range suitable for automotive/industrial environments; evaluated with reference designs.
Notes: packaging is LTM4646EY#PBF (µModule). For exact voltage ranges, current per rail, and PMBus commands, refer to the datasheet and PMBus guide.
