LTM4600HVMPV#PBF

LTM®4600HV is a complete 10A, DC/DC step-down power supply with up to 28V input operation. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over an input voltage range of 4.5V to 28V, this supports an output voltage range of 0.6V to 5V, set by a single resistor. This high-efficiency design delivers 10A continuous current (12A peak), needing no heat sinks or airflow to meet power specifications. Only bulk input and output capacitors are needed to finish the design. The low profile package (2.82mm) enables the utilization of unused space on the bottom of PC boards for high-density points of load regulation. Application includes telecom and networking equipment, military and avionics systems, industrial equipment, and point of load regulation, servers.
