The LTM4630EV#PBF is a dual/single output switching mode step-down DC/DC µModule® Regulator includes the switching controllers, power FETs, inductors and all supporting components. Operating from an input voltage range of 4.5 to 15V, the LTM4630 supports two outputs each with an output voltage range of 0.6 to 1.8V, each set by a single external resistor. Its high efficiency design delivers up to 18A 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 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.
