The LTM®4675 is a dual 9A or single 18A step-down μModule® (micromodule) DC/DC regulator with 40ms turn-on time. It features remote configurability and telemetry-monitoring of power management parameters overPMBus— anopenstandardI 2C-baseddigitalinterface protocol . The LTM4675 is comprised of fast analog control loops, precision mixed-signal circuitry, EEPROM, power MOSFETs, inductors and supporting components. TheLTM4675’s 2-wire serial interface allowsoutputs tobe margined, tunedandrampedupanddownatprogrammable slew rates with sequencing delay times. Input and output currents andvoltages, outputpower, 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 andDC1613 USB-to-PMBus converter and demo kits are available. The LTM4675 is offered in a 16mm × 11.9mm × 3.51mm BGA package available with SnPb or RoHS compliant terminal finish
