14-08-2019 | Analog Devices | Power

Analog Devices LTM4664 Step-Down µModule Regulator is a complete non-isolated 48V input high-efficiency regulator with dual 25A outputs. The switching controllers, inductors, power MOSFETs, and supporting components are incorporated. Only external capacitors are needed to complete the design. Working over a 30V to 58V input voltage range, the device supports an output voltage of 0.5V to 1.5V at up to 75W. An intermediate output at 25% VIN is also offered.


The dual 25A regulators use precision data acquisition circuitry, digitally programmable analog control loops, and EEPROM with ECC. The device’s two-wire serial interface enables the 25A outputs to be margined, tuned and ramped up and down at programmable slew rates and sequencing delay times. True input current sense, input and output power, output currents, and voltages, temperatures, uptime and peak values are all readable.






Typical applications include 48V systems, computer and networking equipment, electronic test equipment, and storage systems.
