The LTM4613MPV#PBF 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 LTM4613MPV#PBF 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.
High switching frequency and an adaptive on-time current mode architecture enables a very fast transient response to line and load changes without sacrificing stability.
The on-board input filter and noise cancellation circuits achieve low noise coupling, thus effectively reducing the electromagnetic interference (EMI)—see Figure 7. Furthermore, the DC/DC μModule® regulator can be synchronized with an external clock to reduce undesirable frequency harmonics and allow PolyPhase® operation for high load currents.
The LTM4613MPV#PBF is offered in a space saving and thermally enhanced 15mm × 15mm × 4.32mm LGA package, which enables utilization of unused space on the bottom of PC boards for high density point-of-load regulation. The LTM4613MPV#PBF is Pb-free and RoHS compliant.
