General part information

LTM4647 Series

The LTM4647 is a complete 30A output switching mode step-down DC/DC μModule®(power module) regulator. Included in the package are the switching controller, power FETs, inductor and all supporting components. Operating over an input voltage range of 4.7V to 15V, the LTM4647 supports an output voltage range of 0.6V to 1.8V, set by a single external resistor. Only a few input and output capacitors are needed.Its high efficiency design delivers 87% efficiency from 12V input to 1.0V output with 30A continuous load current. High switching frequency and a current-mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The device supports frequency synchronization, programmable multiphase operation, N+1 phase redundancy, and output voltage tracking for supply rail sequencing.Fault protection features include overvoltage and overcurrent protection. The power module is offered in a space saving 9mm × 15mm × 5.01mm BGA package. The LTM4647 is available with SnPb (BGA) or RoHS compliant terminal finish.ApplicationsTelecom, Networking and Industrial EquipmentPoint of Load Regulation
