The LTM4677 is a dual 18A or single 36A step-down μModule® (power module) DC/DC regulator with 40ms turn0on time. It features remote configurability and telemetry-monitoring of power management parameters over PMBus— an open standard I2C-based digital interface protocol. The LTM4677 is comprised of fast analog control loops, precision mixedsignal circuitry, EEPROM, power MOSFETs, inductors and supporting components.
The LTM4677’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 LTM4677 is pin compatible with the LTM4676A (dual 13A) and is offered in a 16mm × 16mm × 5.01mm BGA package available with SnPb or RoHS compliant terminal finish.
