LTM4686EV#PBF

LTM4686 is a dual 10A (12A peak) or single 20A (24A Peak) step-down µModule® (micromodule) DC/DC regulator with 39ms turn-on time. It features remote configurability and telemetry-monitoring of power management parameters over PMBus an open standard I²C-based digital interface protocol. It is comprised of fast analog control loops, precision mixed signal circuitry, EEPROM, power MOSFETs, inductors and supporting components. This device’s 2-wire serial interface enables voltage margining and sequencing, and telemetry readback of currents, voltages, power, temperature, uptime and peak values. Pin-strap resistors configure start-up settings. It is widely used in application such as system optimization in prototype and production etc.
