LTM4604

www.DataSheet4U.com LTM4604 Low Voltage, 4A DC/DC µModuleTM with Tracking DESCRIPTION The LTM®4604 is a complete 4A switch mode DC/DC power supply. 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 output capacitors are needed to complete the design. The low profile package (2.3mm) 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 space saving and thermally enhanced 15mm × 9mm × 2.3mm LGA package and is Pb free and RoHS compliant. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation. μModule and UltraFast are trademarks of Linear Technology Corporation.
