1V, 20A Fault-Protected Load Powered by Paralleled LTM4641—from Up to 38VIN. cf. Typical Performance Characteristics

 

 

The LTM4641 is a switch mode step-down DC/DC μModule® (micromodule) regulator with advanced input and load protection features. Trip detection thresholds for the following faults are customizable: input undervoltage, overtemperature, input overvoltage and output overvoltage. Select fault conditions can be set for latchoff or hysteretic restart response—or disabled. Included in the package are the switching controller and housekeeping ICs, power MOSFETs, inductor, overvoltage drivers, biasing circuitry and supporting components. Operating from input voltages of 4V to 38V (4.5V start-up), the device supports output voltages from 0.6V to 6V, set by an external resistor network remote sensing the point-of-load’s voltage.
