TYPICAL APPLICATION FEATURES DESCRIPTION Ultrathin Dual 14A or Single 28A μModule Regulator with Digital Power System Management The LTM®4686B is a dual 14A (17A peak) or single 28A (34A peak) step-down µModule® (micromodule) DC/ DC regulator with 39ms turn-on time. It features remote configurability and telemetry-monitoring of power man- agement parameters over PMBus—an open standard I2C-based digital interface protocol . The LTM4686B is comprised of fast analog control loops, precision mixed- signal circuitry, EEPROM, power MOSFETs, inductors and supporting components. A video on ultrathin module products is available on the website. Click here . The LTM4686B’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, temperature, uptime and peak values are readable. Custom configuration of the EEPROM contents is not required. Pin-strap resistors con- figure start-up settings. The LTpowerPlay® GUI, DC1613 USB-to-PMBus converter, DC2086 programming adapter and demo kits are available. Pb-free and RoHS compliant, the LTM4686B is available in a 16mm × 11.9mm × 1.82mm LGA package.
