Description
General part information
LTM4638 Series
The LTM4638 is a complete 15A step-down switching 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 supports 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 output capacitors are needed.The LTM4638 supports selectable discontinuous mode operation and output voltage tracking for supply rail sequencing. 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.ApplicationsTelecom, Datacom, Networking and Industrial EquipmentMedical Diagnostic EquipmentData Storage Rack Units and CardsTest and Debug Systems
