DESCRIPTION
The LTM®4613 is a complete, ultralow noise, 8A 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 5V to 36V, the LTM4613 supports an output voltage range of 3.3V to 15V, set by a single external resistor. Only bulk input and output capacitors are needed to finish the design.
