LTM4700 Description

The LTM4700 is a dual 50A or single 100A step-down µModule^® (power module) DC/DC regulator featuring remote configurability and telemetry-monitoring of power management parameters over PMBus— an open standard I²C-based digital interface protocol. The LTM4700 is comprised of fast analog control loops, precision mixed signal circuitry, EEPROM, power MOSFETs, inductors and supporting components. The LTM4700 product video is available on website.

The LTM4700's 2-wire serial interface allows outputs to be margined, tuned and ramped up and down at programmable slew rates with sequencing delay times. Input and output currents and voltages, output power, temperatures, uptime and peak values are readable. Custom configuration of the EEPROM contents is not required. At start-up, output voltages, switching frequency, and channel phase angle assignments can be set by pin-strapping resistors. The LTpowerPlay^® GUI and DC1613 USB-to-PMBus converter and demo kits are available.

The LTM4700 is offered in a 15mm × 22mm × 7.87mm BGA package available with SnPb or RoHS compliant terminal finish.
