The LTM4631 is a dual 10A or single 20A output switching mode step-down DC/DC μModule® (power module) regulator. Included in the package are the switching controller, power FETs, inductors and all supporting components. Operating from an input voltage range of 4.5V to 15V, the LTM4631 supports two outputs each with an output voltage range of 0.6V to 1.8V, each set by a single external resistor. Its high efficiency design delivers up to 10A continuous current for each output. Only a few input and output capacitors are needed.
The device supports frequency synchronization, multiphase operation, Burst Mode operation and output voltage tracking for supply rail sequencing and has an onboard temperature diode for device temperature monitoring. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
Fault protection features include overvoltage and overcurrent protection. The LTM4631 is offered in an ultrathin 16mm × 16mm × 1.91mm LGA and 16mm x 16mm x 2.51mm BGA packages. The LTM4631 is available with SnPb (BGA) or ROHS compliant terminal finish.
