The LTM®4682 is a quad 31.25A or single 125A step-down power μModule®(power micromodule) DC/DC regulator featuring remote configurability and telemetry monitoring of power management parameters over PMBus. The LTM4682 is comprised of digitally programmable analog control loops, and is optimized for higher bandwidth and transient response.The LTM4682’s 2-wire serial interface allows outputs to be margined, tuned, and ramped up and down at programmable slew rates with sequencing delay times. True input current sense, output currents, output 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. TheLTpowerPlay®graphical user interface (GUI), theDC1613AUSB-to-PMBus converter, and evaluation kits are available.The LTM4682 is offered in a 15mm × 22mm × 5.71mm BGA package available with an SnPb or a RoHS-compliant terminal finish.APPLICATIONSMulti-Rail Processor Power, Configurable Core Power

The LTM4693 is an ultrathin, highly efficient, 2A buck-boost μModule®DC/DC converter that operates from input voltages above, below or equal to the output voltage. Included in the package are the switching controller, power MOSFETs, inductor and support components. The LTM4693’s advanced topology provides a continuous transfer through all operating modes. VINoperation from 2.6V to 5.5V covers a wide variety of power sources including typical 3.3V and 5V. Output voltage ranging from 1.8V to 5.5V is set by an external resistor. Only a few external components are needed for a typical application.Selectable Burst Mode®operation reduces quiescent current to 15μA, ensuring high efficiency across the entire load range. To optimize applications for highest efficiency, the switching frequency can be programmed between 1MHz to 4MHz or synchronized to an external clock for noise sensitive circuits.LTM4693 is available in ultrathin, 3.5mm × 4mm ×1.25mm LGA Package. The LTM4693 is Pb-free and RoHS compliant.APPLICATIONSTelecom, Datacom (Optical Modules) and Industrial EquipmentMedical and Industrial InstrumentsWireless RF TransmitterBattery Powered System
