Beschreibung

The LTM®4664 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.
