LTM4627IY is a complete 15A output high efficiency switch mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductor and compensation components. Operating over an input voltage range from 4.5V to 20V, the LTM4627 supports an output voltage range of 0.6V to 5V, set by a single external resistor. Only a few input and output capacitors are needed.
Current mode operation allows precision current sharing of up to four LTM4627 regulators to obtain 60A output. 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, multiphase/current sharing operation, Burst Mode operation and output voltage tracking for supply rail sequencing.
LTM4627IY is offered in thermally enhanced 15mm × 15mm × 4.32mm LGA and 15mm × 15mm × 4.92mm BGA packages. The LTM4627 is available with SnPb (BGA) or RoHS compliant terminal finish.
