DESCRIPTION
The LTM ? 4601 is a complete 12A step-down switch mode
DC/DC power supply with onboard switching controller,
MOSFETs, inductor and all support components. The
μModule ? regulator is housed in small surface mount
15mm × 15mm × 2.82mm LGA and 15mm × 15mm ×
3.42mm BGA packages. Operating over an input voltage
range of 4.5V to 20V, the LTM4601 supports an output
voltage range of 0.6V to 5V as well as output voltage
tracking and margining. The high efficiency design deliv-
ers 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.
A high switching frequency and adaptive on-time current
mode architecture deliver a very fast transient response
to line and load changes without sacrificing stability. An
onboard differential remote sense amplifier can be used
to accurately regulate an output voltage independent of
load current. The onboard remote sense amplifier is not
available in the LTM4601-1.
