DESCRIPTION
The LTM®4604A is a complete 4A switch mode step-down µModule®(micromodule) regulatorwith±1.75%maximum 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 2.375V to 5.5V, the LTM4604A 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 input and output capacitors are needed to complete the design.
