Description

The LTM4676A is a dual 13A or single 26A step-down ?Module? (micromodule) DC/DC regulator with 40ms turn-on time. It features remote configurability and telemetry-monitoring of power management parameters over PMBus? an open standard I2C-based digital interface protocol . The LTM4676A is comprised of fast analog control loops, precision mixed-signal circuitry, EEPROM, power MOSFETs, inductors and supporting components.The LTM4676A?s 2-wire serial interface allows outputs to be margined, tuned and ramped up and down at programmable slew rates with sequencing delay times. Input and output currents and voltages, output power, temperatures, uptime and peak values are readable. At start-up, output voltages, switching frequency, and channel phase angle assignments can be set by pin-strapping resistors. The LTpowerPlay? GUI and DC1613 USB-to-PMBus converter and demo kits are available.The LTM4676A is pin-compatible and the improved performance version of the LTM4676.
