Product Overview

The LTM4619EV#PBF is a complete dual or single step-down DC/DC µModule® Regulator includes the switching controller, power FETs, inductor and all support components. Operating over input voltage ranges of 4.5 to 26.5V, the LTM4619 supports two outputs with voltage ranges of 0.8 to 5V, each set by a single external resistor. Its high efficiency design delivers 4A continuous current for each output. High switching frequency and 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 pulse-skipping mode can be selected for light load operations. Fault protection features include overvoltage protection, overcurrent protection and fold-back current limit for short-circuit protection.
