LTM4604 Description

The LTM4604 is a complete 4A switch mode step-down μModule® (power module) regulator. Included in the package are the switching controller, power FETs, inductor and all support components. Operating over an input voltage range of 2.375V to 5.5V, the LTM4604 supports an output voltage range of 0.8V to 5V, set by a single resistor. This high efficiency design delivers up to 4A continuous current (5A peak). Only bulk input and output capacitors are needed to complete the design.

The low profile package (2.32mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. 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 output voltage tracking for supply rail sequencing.

Fault protection features include foldback current protection, thermal shutdown and a programmable soft-start function. The LTM4604 is offered in a RoHS compliant 15mm × 9mm × 2.32mm LGA package.

For easier PC board layout and assembly due to increased spacing between land grid pads, please refer to the LTM4604A.
