LTM4626EY#PBF

LTM4626EY#PBF is a quad-output, step-down µModule DC-DC regulator from Analog Devices (Linear Technology). The device integrates the power MOSFETs, controller, inductors, and filtering into a single compact module, delivering four independently regulated, low-noise rails from a common input. The EY suffix denotes a specific package variant, and PBF indicates Pb-free packaging. Key features commonly include a wide input range, externally adjustable outputs with feedback, remote sense, current-sharing and sequencing, high efficiency, overcurrent/overtemperature protection, undervoltage lockout, and fault reporting. It is well-suited for space-constrained boards powering FPGAs, CPUs, memory, and other multi-rail loads. For exact specifications (input range, per-rail current, output voltages, footprint), consult the datasheet and layout guidelines.

Here are the key features of the LTM4626EY#PBF (extended-temp, Pb-free) μModule regulator:
- Dual 2‑phase synchronous buck regulators in a single compact μModule package
- Integrated inductor, MOSFETs, controller, and passives for a complete power module
- PMBus/I2C-compatible digital interface for remote voltage programming, margining, sequencing, and telemetry
- Wide input voltage range with high efficiency from multi‑phase operation
- Independent two outputs (or configurable to share current); outputs are programmable and can be sequenced
- Remote sense for accurate output regulation; margining capability
- Protections: overcurrent/short-circuit, overvoltage/undervoltage, overtemperature, UVLO; typically with hiccup fault behavior
- Soft-start and user-controlled sequencing options
- Status and fault outputs (PG/FAULT) for system monitoring
- Industrial temperature range option (EY) and RoHS Pb-free (PBF) packaging
Note: exact voltage ranges, current capability per rail, and sequencing specifics are in the datasheet for the specific revision.
