Description
General part information
LTM4619 Series
The LTM4619 is a complete dual 4A or single 8A stepdown DC/DC μModule®(power module) regulator. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over input voltage ranges of 4.5V to 26.5V, the LTM4619 supports two outputs with voltage ranges of 0.8V to 5V, each set by a single external resistor. Its high efficiency design delivers 4A continuous current (5A peak) for each output.High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The two outputs are interleaved with 180° phase to minimize the ripple noise and reduce the I/O capacitors. The device supports frequency synchronization and output voltage tracking for supply rail sequencing. Burst Mode operation or pulseskipping mode can be selected for light load operations.Fault protection features include overvoltage protection, overcurrent protection and foldback current limit for short-circuit protection.The low profile package (2.82mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The power module is offered in a 15mm × 15mm × 2.82mm LGA package. The LTM4619 is RoHS compliant with Pb-free finish.ApplicationsTelecom and Networking EquipmentServersStorage CardsATCA CardsIndustrial EquipmentPoint of Load Regulation
