OUT) at 40A
n Overcurrent Foldback Protectio 16mm × 16mm × 7.07mm BGA Package The LTM®4636 is a 40A step-down µModule (power
module) switching regulator with a stacked inductor as a
heat sink for quicker heat dissipation and cooler operation
in a small package. The exposed inductor permits direct
contact with airflow from any direction. The LTM4636
can deliver 40W (12VIN, 1VOUT, 40A, 200LFM) with only
40°C rise over the ambient temperature. Full-power 40W
is delivered, up to 83°C ambient and half-power 20W is
supported at 110°C ambient. n n n n The LTM4636 operates at 92%, 90% and 88% efficiency, …
