LTM4700EY#PBF - Dual 50A/100A µModule Regulator | Analog Devices
MPN: LTM4700EY#PBF ✓ فعالLTM4700EY#PBF جائزہ
A µModule (micro-module) regulator is a complete DC/DC converter system-in-package that includes the controller, power switches, inductors, and compensation, reducing external component count and design risk. It belongs to the hierarchy: µModule regulator -> power module -> DC/DC converter -> power management IC -> semiconductor. This integration enables compact, high-current point-of-load (PoL) solutions for advanced processors, FPGAs, and ASICs.
Key features include dual 50A or single 100A output capability, input voltage range of 4.5V to 16V, and adjustable output voltage from 0.5V to 1.8V per channel. The device supports PMBus for digital power system management, allowing real-time telemetry of voltage, current, and temperature, as well as configuration of output voltage, sequencing, and fault thresholds. It operates over a 0°C to 125°C internal temperature range (E-grade), with -40°C to 125°C assured by design.
The LTM4700 integrates high-efficiency power stage with low on-resistance MOSFETs and low-loss inductors, achieving high conversion efficiency in a compact BGA package. The digital interface enables precise voltage accuracy and dynamic load response, while the EEPROM stores configuration settings for autonomous startup. The device includes fault protection features such as overcurrent, overvoltage, and overtemperature monitoring.
Typical applications include high-current PoL regulation for FPGAs, ASICs, GPUs, and processors in data centers, networking equipment, and industrial systems. The PMBus interface makes it ideal for systems requiring dynamic voltage scaling, power sequencing, and health monitoring.
When designing with the LTM4700, ensure adequate thermal management due to high output currents. The BGA package requires a multi-layer PCB with thermal vias to dissipate heat effectively. Use the PMBus interface to configure and monitor the regulator for optimal performance.

ڈیزائن نوٹس
The LTM4700EY#PBF can dissipate significant power at 100A output. Ensure adequate thermal management by using a multi-layer PCB with thermal vias under the BGA package. The datasheet recommends a minimum of 4 layers with 2oz copper for the power and ground planes. Consider adding a heatsink or forced airflow for high ambient temperature operation.
Place input and output capacitors close to the module pins to minimize parasitic inductance. Use low-ESR ceramic capacitors for high-frequency decoupling. The datasheet provides recommended capacitor values and placement guidelines. Ensure the PCB layout supports high current paths with wide traces and multiple vias.
Do not exceed the maximum input voltage of 16V. Ensure the PMBus address is correctly configured using the address pins. The FAULT pins are open-drain and require pull-up resistors. Minimize capacitance on the address pin to ensure accurate detection. Follow the datasheet's layout guidelines to avoid noise issues.
