Description
Introduction to LTM8047MPY
- The LTM8047MPY is a μModule DC-DC regulator from Analog Devices’ LTM family. It’s a fully integrated step-down converter in a single compact package (the MPY variant), combining the switching regulator, power MOSFETs, inductor, and essential support circuitry.
- Benefits: high efficiency, fast transient response, small PCB footprint, and built-in protections (overcurrent/short-circuit, thermal shutdown, undervoltage lockout). Output voltage is adjustable via an external feedback network; it typically supports a wide input range with fast startup.
- Typical use: power rails for FPGAs, GPUs, ASICs, and other digital ICs where space and BOM are critical.
- Design notes: reference the datasheet and evaluation board for pinout, recommended external components, thermal considerations, and layout guidelines.

Features
LTM8047MPY is a high-efficiency, monolithic µModule DC-DC regulator with an integrated inductor, MOSFETs and driver in a compact MPY package. Key features:
- Fully integrated power stage and inductor; external feedback network sets output.
- Wide input voltage range suitable for multipoint power rails.
- Adjustable output voltage with fast transient response.
- High efficiency and compact footprint (no external power components required besides feedback parts).
- Synchronous rectification for reduced losses.
- Remote sense for improved regulation under load.
- Protections: overcurrent/short-circuit, overtemperature, input undervoltage/overvoltage.
- Enable input and Power-Good signaling for sequencing.
- Soft-start to limit inrush and improve reliability.
- Typical switching frequency in the MHz range for small capacitors.
- RoHS-compliant and suitable for CPU cores, GPUs, and high-current rails.
Note: exact voltage/current specs and pinout vary by revision; consult the current datasheet for precise limits and configuration options.
