Ultralow Noise
36VIN, 15VOUT, 5A,
DC/DC Module Regulator
The LTM4612 is a complete, ultralow noise, high voltage
inputandoutput,5AswitchingmodeDC/DCpowersupply.
Includedinthepackagearetheswitchingcontroller,power
FETs, inductor and all support components. Operating
over an input voltage range of 5V to 36V, the LTM4612
supports an output voltage range of 3.3V to 15V, set by a
single 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 onboard input filter and noise cancellation circuits
achieve low noise coupling, thus effectively reducing the
electromagnetic interference (EMI)—see Figures 4 and 8.
Furthermore, the DC/DC Module can be synchronized
with an external clock to reduce undesirable frequency
harmonics and allow PolyPhase operation for high load
currents.
The LTM4612 is offered in a space saving and thermally
enhanced 15mm
× 15mm × 2.8mm LGA package, which
enables utilization of unused space on the bottom of PC
boards for high density point-of-load regulation. The
LTM4612 is Pb-free and RoHS compliant.
