ADI's LTM4700 is a dual 50 A or single 100 A 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’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. Output voltages, switching frequency, and channel-phase angle assignments can be set by pin-strapping resistors at start-up. The LTpowerPlay® GUI and the DC1613 USB-to-PMBus converter and demo kits are available.
The LTM4700 is offered in a 15 mm × 22 mm × 7.87 mm BGA package available with SnPb or RoHS compliant terminal finish.
