Description

General part information

LTM4636 Series

The LTM4636-1 is a 40A step-down μModule®(power module) switching regulator with stacked inductor as a heat sink for heat dissipation and cooler operation in a small package. The LTM4636-1 detects overtemperature and input/output overvoltage conditions and can trip an upstream power supply or circuit breaker to protect itself and its load. The exposed inductor as a heat sink permits direct contact with airflow from any direction. The LTM4636-1 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 LTM4636-1 operates at 92%, 90% and 88% efficiency delivering 15A, 30A and 40A, respectively, to a 1V load (12VIN). The μModule regulator is scalable where four in current sharing deliver 160W with only 40°C rise and 88% efficiency (12VIN, 1VOUT, 400LFM). The LTM4636-1 is offered in 16mm × 16mm × 7.07mm BGA package.NotesLTM4636Simpler circuits and fewer featuresLTM4636-1Extra internal circuitry for detecting overtemperature and input/output overvoltage conditionsAPPLICATIONSTelecom Servers and Networking EquipmentIndustrial Equipment and Medical Systems
