The LTM4673 is a quad output, dual 12A and dual 5A, switching mode DC/DC step-down μModule (powermodule) regulator integrated with 4-channel Power System Manager used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry, and create fault logs. Operating over an input voltage range of 4.5V to 15V, the LTM4673 supports an output voltage range of 0.6V to 3.3V for 12A channels and 0.6V to 5.5V for 5A channels. Only bulk input and output capacitors are needed.The LTM4673’s 2-wire serial interface allows outputs to be precisely margined, tuned and programmable sequenced up and down. An internal 16-bit ADC monitors and supervises input and all four output voltages, currents and temperatures. Faults can be programmed for overcurrent and undercurrent, voltage and temperature threshold limits for four output channels as well as over and undervoltage for the input.The LTM4673 is offered in a 16mm × 16mm × 4.72mm BGA package with RoHS compliant terminal finish.APPLICATIONSTelecom, Networking and Industrial EquipmentMulti-Rail Point of Load RegulationFPGAs, DSPs and ASICs Application
