Description

The LTM4636 is a 40A step-down ?Module (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.The LTM4636 operates at 92%, 90% and 88% efficiency, delivering 15A, 30A and 40A, respectively, to a 1V load (12VIN). The ?Module regulator is scalable such that four ?Modules in current sharing mode deliver 160W with only 40?C rise and 88% efficiency (12VIN, 1VOUT, 400LFM). The LTM4636 is offered in a 16mm ? 16mm ? 7.07mm BGA package.
