LTM4664A Description

The LTM4664A is a complete nonisolated 48V input high efficiency step-down μModule® regulator with dual 30A 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 LTM4664A supports an output voltage of 0.5V to 1.5V at up to 75W. An intermediate output at 25% • VIN is also available. The LTM4664A product video is available on the website.

The LTM4664A dual 30A regulators utilize digitally programmable analog control loops, precision data acquisition circuitry and EEPROM with ECC. The LTM4664A’s 2-wire serial interface allows the 30A 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 for Dual 30A Power System Management (PSM) channels.
