LTM4700
Description
The LTM®4700 is a dual 50A or single 100A 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. The LTM4700 is comprised of fast analog control loops, precision mixedsignal circuitry, EEPROM, power MOSFETs, inductors and supporting components.
