The LTM4664 is a complete non-isolated 48V input high efficiency step-down µModule® regulator with dual 25A outputs. The switching controllers, power MOSFETs, inductors and supporting components are included. Only external capacitors are needed to complete the design. Operating over a 30V to 58V input voltage range, the LTM4664 supports an output voltage of 0.5V to 1.5V at up to 75W. An intermediate output at 25% • VIN is also available. The LTM4664 product video is available on the website.

The LTM4664 dual 25A regulators utilize digitally programmable analog control loops, precision data acquisition circuitry and EEPROM with ECC. The LTM4664’s 2-wire serial interface allows the 25A outputs to be margined, tuned and ramped up and down at programmable slew rates and sequencing delay times. True input current sense, output currents and voltages, input and output power, temperatures, uptime and peak values are all readable.

LTM4664 Demo Board | 48VIN, Dual 25A μModule Regulator With Digital Power System Management

Product Detail

Demonstration circuit 2672A-A is a complete non-isolated 48V input, dual-output, high efficiency, high density µModule regulator with 30V to 58V input range. Each output can supply 25A maximum load current. The demo board has a LTM4664 µModule regulator, which is a dual 25A or single 50A step-down regulator with digital power system management. Please see the LTM4664 datasheet for more detailed information.

DC2672A-A powers up to default settings and produces power based on configuration resistors without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter. To fully explore the extensive power system management features of the part, download the GUI software LTpowerPlay™ onto your PC and use ADI’s I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part on the fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.
