TYPICAL APPLICATION
2.7V to 5.5V Input to 1.8V Output DC/DC μModule ? Regulator
DESCRIPTION
The LTM ? 4608 is a complete 8A switch mode DC/DC
power supply. Included in the package are the switching
controller, power FETs, inductor and all support compo-
nents. Operating over an input voltage range of 2.7V to
5.5V, the LTM4608 supports an output voltage range of
0.6V to 5V, set by a single external resistor. This high ef-
ficiency design delivers up to 8A continuous current (10A
peak). Only bulk input and output capacitors are needed.
The low profile package (2.82mm) enables utilization
of unused space on the back side of PC boards for high
density point-of-load regulation. The high switching
frequency and a current mode architecture enable a very
fast transient response to line and load changes without
sacrificing stability. The device supports frequency syn-
chronization, programmable multiphase and/or spread
spectrum operation, output voltage tracking for supply
rail sequencing and voltage margining.
Fault protection features include overvoltage protection,
overcurrent protection and thermal shutdown. The power
module is offered in a compact and thermally enhanced
9mm × 15mm × 2.82mm LGA package. The LTM4608 is
RoHS compliant with Pb-free finish.
