DESCRIPTION

20VIN, 15A Step-Down DC/DC

µModule Regulator

The LTM®4638 is a complete 15A step-down switch-

ing mode µModule (power module) regulator in a tiny

6.25mm × 6.25mm × 5.02mm BGA package. Included

in the package are the switching controller, power FETs,

inductor and support components. Operating over an

input voltage range of 3.1V to 20V, the LTM4638 sup-

ports an output voltage range of 0.6V to 5.5V, set by a

single external resistor. Its high efficiency design delivers

up to 15A continuous output current. Only bulk input and

outputcapacitorsareneeded.TheLTM4638productvideo

is available on the website.

The LTM4638 supports selectable discontinuous mode

operation and output voltage tracking for supply rail se-

quencing. Its high switching frequency and current mode

control enable a very fast transient response to line and

load changes without sacrificing stability.

Fault protection features include overvoltage, overcurrent

and overtemperature protection.

The LTM4638 is available with SnPb or RoHS compliant

terminal finish.
