ANALOG DEVICES LTM4678EY#PBF

LTM4678 is a dual 25A or single 50A step-down µModule® (power module) DC/DC regulator featuring remote configurability and telemetry-monitoring of power management parameters over PMBus an open standard I²C-based digital interface protocol. It is comprised of digitally programmable analogue control loops, precision mixed-signal circuitry, EEPROM, power MOSFETs, inductors and supporting components. This device’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. It is used in application like system optimization, characterization and data mining in prototype, production and field environments etc.
