TYPICAL APPLICATION
12V/8A Ultralow Noise μModule with 24V to 36V Input
EN55022B Compliant
36V IN , 15V OUT , 8A,
DC/DC μModule Regulator
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.
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 Figure 7.
Furthermore, the DC/DC μModule ? regulator can be syn-
chronized with an external clock to reduce undesirable
frequency harmonics and allow PolyPhase ? operation for
high load currents.
The LTM4613 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
LTM4613 is Pb-free and RoHS compliant.
