Description
General part information
LTM4683 Series
The LTM4683 is a quad 31.25A or single 125A stepdown μModule®(power micromodule) DC/DC regulator featuring remote configurability and telemetry monitoring of power management parameters over PMBus. The LTM4683 is comprised of digitally programmable analog control loops, and is optimized for higher bandwidth and transient response.The LTM4683'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 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®graphical user interface (GUI), DC1613A USB-to-PMBus converter, and evaluation kits are available.The LTM4683 is offered in a 15mm × 22mm × 5.71mm BGA package available with a RoHS-compliant terminal finish.APPLICATIONSMulti-Rail Processor Power, Configurable Core Power
