LTM4620MPY#PBF

LTM4620MPY#PBF is Analog Devices’ multi-output μModule DC-DC regulator. It integrates the power stage (MOSFETs and inductor), controller, feedback, and PMBus logic into a single compact module, delivering multiple regulated rails from a common input.
Key features:
- PMBus digital control for programming, monitoring, sequencing, and fault handling
- Remote sense, voltage tracking/sequencing, and multiple protection features (OC/OV/UV, thermal)
- Pb-free package (PBF) with a specific MPY package code
- Suitable for high-density power delivery in complex boards
Common applications:
- CPU/FPGA/ASIC power rails, embedded and telecom systems, high-performance computing.
Note:
- For exact specifications (input range, per-rail outputs, current capability, efficiency, sequencing options), consult the LTM4620/LTM4620MPY#PBF datasheet and product page.

Here are the key features of the LTM4620MPY#PBF (µModule multi-rail regulator):
- Six independent regulator channels in a single module (multi-rail power delivery)
- Integrated power stages and inductors; no external inductors required
- Wide input voltage range suitable for multiphase/mission-critical rails
- Flexible output voltages per rail with external feedback/options for adjustment
- Remote sensing for accurate regulation and precise voltage tracking/sequencing
- I2C/PMBus-compatible control and telemetry for voltage, current, and temperature
- Per-rail overcurrent protection, overvoltage protection, and thermal shutdown
- Soft-start, fault reporting, and latch/short-circuit protection
- Output tracking and sequencing to meet load-rail power-up requirements
- Compact, RoHS-compliant MPY package suitable for space-constrained designs
- High efficiency across operating range with thermal management features
Note: For exact voltage ranges, current capabilities per rail, and diagnostic/programmable options, consult the latest LTM4620 data sheet and product documentation.

Pb-free BGA µModule package. (PBF indicates Pb-free RoHS; MPY is the package code for the LTM4620 µModule in a BGA form factor.)

Pin count: 48-ball BGA (48 pins).
Function: LTM4620MPY#PBF is a fully integrated µModule step‑down (synchronous switching) DC/DC regulator. It contains controller, MOSFETs, inductors and compensation and provides multi‑phase synchronous buck regulation. Package pins include power inputs (VIN/PVIN), power grounds (PGND), outputs/VOUT and sense pins, control/enable (RUN/SS, MODE/TRACK), status (PG/FAULT), monitoring/communication and support pins. "#PBF" = Pb‑free/RoHS.

The LTM4620MPY#PBF is manufactured by Analog Devices, Inc. (formerly Linear Technology).
Analog Devices is a multinational semiconductor company that specializes in analog, mixed-signal, and DSP integrated circuits.

LTM4620MPY#PBF is a multi‑output, PMBus‑controlled DC‑DC µModule. Typical applications include:
