Applications
The LTM®4601AHV is a complete 12A step-down switch
mode DC/DC power supply with onboard switching con-
troller, MOSFETs, inductor and all support components.
The µModule regulator is housed in a small surface mount
15mm × 15mm × 2.82mm LGA or 15mm × 15mm ×
3.42mm BGA package. The LTM4601AHV LGA and BGA
packages are designed with redundant mounting pads to
enhance solder-joint strength for extended temperature
cycling endurance. Operating over an input voltage range
of 4.5V to 28V, the LTM4601AHV supports an output volt-
age range of 0.6V to 5V as well as output voltage tracking
and margining. The high efficiency design delivers 12A
continuous current (14A peak). Only bulk input and output
capacitors are needed to complete the design.
The low profile and light weight package easily mounts
in unused space on the back side of PC boards for high
density point of load regulation. The µModule regulator
can be synchronized with an external clock for reducing
undesirable frequency harmonics and allows PolyPhase®
operation for high load currents.
An onboard differential remote sense amplifier can be used
to accurately regulate an output voltage independent of
load current. The LTM4601AHV is available with SnPb or
RoHS compliant terminal finish.
