The LTM4618 step-down µModule® regulator delivers up to 6A from an input supply ranging from 4.5V to 26.5V. An accurate output voltage in the range of 0.8V to 5V is determined by a single external resistor. The external clock input supports a uniform switching frequency within the system for noise isolation. Packaged within a 9mm x 15mm x 4.32mm land grid array package, the LTM4618 is compatible with surface mount reflow techniques and is RoHS compliant.
