LTM4606

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.

High switching frequency and an adaptive on-time current mode architecture enables a very fast transient response to line and load changes without sacrifi cing stability. The device supports output voltage tracking and output voltage margining.

Furthermore, the Module™ can be synchronized with an external clock for reducing undesirable frequency harmonics and allows PolyPhase^® operation for high load currents.

The LTM4606 is offered in a space saving and thermally enhanced 15mm * 15mm * 2.8mm LGA package, which enables utilization of unused space on the bottom ofPC boards for high density point of load regulation. The LTM4606 is Pb-free and RoHS compliant.
