LTM4600EV

The LTM4600EV belongs to LTM4600 family which is a complete 10A, DC/DC step down power supply. Operating over an input voltage range of 4.5V to 20V, the LTM4600 supports an output voltage range of 0.6V to 5V, set by a single resistor. The LTM4600 is packaged in a thermally enhanced, compact (15mm * 15mm) and low profile (2.8mm) over-molded Land Grid Array (LGA) package suitable for automated assembly by standard surface mount equipment. The LTM4600 is Pb-free and RoHS compliant. Included in the package are the switching controller, power FETs, inductor, and all support components. The low profile package (2.8mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. High switching frequency and an adaptive on-time current mode architecture enables a very fast transient response to line and load changes without sacrificing stability. This high efficiency design delivers 10A continuous current (14A peak), needing no heat sinks or airfiow to meet power specifications. Only bulk input and output capacitors are needed to finish the design. Fault protection features include integrated overvoltage and short circuit protection with a defeatable shutdown timer. A built-in soft-start timer is adjustable with a small capacitor.
