The LTM?4606 is a complete ultralow noise high voltage 6A switching mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductor, and all support components. The on-board input fi lter and noise cancellation circuits achieve low noise operation, thus effectively reducing the electromagnetic interference (EMI). Operating over an input voltage range of 4.5V to 28V, the LTM4606 supports an output voltage range of 0.6V to 5V, set by a single resistor. This high effi ciency design delivers 6A continuous current (8A peak). Only bulk input and output capacitors are needed to fi nish the design.
