The LTM4675 is a dual 9A or single 18A step-down μModule® (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 LTM4675 is comprised of fast analog control loops, precision mixed-signal circuitry, EEPROM, power MOSFETs, inductors and supporting components.

The LTM4675’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. 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® GUI and DC1613 USB-to-PMBus converter and demo kits are available.

The LTM4675 is offered in a 16mm × 11.9mm × 3.51mm BGA package available with SnPb or RoHS compliant terminal finish.

LTM4675EY Demo Board | Dual PMBus Buck μModule Regulator, 4.5V ≤ VIN ≤ 17V, VOUT0/VOUT1 = 1V/1.8V @ 9A

Product Detail

Demonstration circuit 2053A is a dual-output, high efficiency, high density, μModule® regulator, operating from a 4.5V to 17V input range. The demo board features the LTM4675 a dual 9A or single 18A step-down regulator with PMBus digital power system management. The default dual output voltages are 1V and 1.8V, but each can be set to a voltage from 0.5V to 5.5V. Each output can supply 9A maximum load current. Please see the LTM4675 data sheet for more detailed information.
