The LTM4645 is a 25A 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 LTM4645 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 about 86% efficiency from 12V input to 1.0V output with 25A 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 × 3.51mm BGA package. The LTM4645 is available with SnPb (BGA) or RoHS compliant terminal finish.
