The LTM4636 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.
The LTM4636 operates at 92%, 90% and 88% efficiency, delivering 15A, 30A and 40A, respectively, to a 1V load (12VIN). The μModule regulator is scalable such that four μModules 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.
