LTM4608AEV#PBF

LTM®4608A is a complete 8A switch mode DC/DC power supply with ±1.75% total output voltage error. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over an input voltage range of 2.7V to 5.5V, this supports an output voltage range of 0.6V to 5V, set by a single external resistor. This high-efficiency design delivers up to 8A continuous current (10A peak). Only bulk input and output capacitors are needed to complete the design. The low profile package (2.82mm) enables the utilization of unused space on the back side of PC boards for high-density point-of-load regulation. Application includes telecom, networking and industrial equipment, storage systems, point of load regulation.

• Complete standalone power supply
