Power Module Description
The LTM4601AHV is a standalone nonisolated switching
mode DC/DC power supply. It can deliver up to 12A of
DC output current with some external input and output
capacitors.Thismoduleprovidespreciselyregulatedoutput
voltageprogrammableviaoneexternalresistorfrom0.6VDC
to 5.0VDC over a 4.5V to 28V wide input voltage. Typical
application schematics are shown in Figures 19 and 20.
The LTM4601AHV has an integrated constant on-time
current mode regulator, ultralow RDS(ON) FETs with fast
switchingspeedandintegratedSchottkydiodes.Thetypical
switching frequency is 850kHz at full load. With current
mode control and internal feedback loop compensation,
the LTM4601AHV module has sufficient stability margins
and good transient performance under a wide range of
operating conditions and with a wide range of output
capacitors, even all ceramic output capacitors.
Current mode control provides cycle-by-cycle fast current
limit. Besides, foldback current limiting is provided in an
overcurrent condition while VFB drops. Internal overvolt-
age and undervoltage comparators pull the open-drain
PGOOD output low if the output feedback voltage exits a
±10% window around the regulation point. Furthermore,
in an overvoltage condition, internal top FET Q1 is turned
off and bottom FET Q2 is turned on and held on until the
overvoltage condition clears.
Pulling the RUN pin below 1V forces the controller into its
shutdown state, turning off both Q1 and Q2. At low load
current, the module works in continuous current mode by
default to achieve minimum output ripple voltage.
When DRVCC pin is connected to INTVCC an integrated
5V linear regulator powers the internal gate drivers. If a
5V external bias supply is applied on the DRVCC pin, then
an efficiency improvement will occur due to the reduced
power loss in the internal linear regulator. This is especially
true at the high end of the input voltage range.
The LTM4601AHV has a very accurate differential remote
sense amplifier with very low offset. This provides for
very accurate output voltage measurement at the load.
The MPGM pin, MARG0 pin and MARG1 pin are used to
supportvoltagemargining,wherethepercentageofmargin
is programmed by the MPGM pin, and the MARG0 and
MARG1 select margining.
The PLLIN pin provides frequency synchronization of the
device to an external clock. The TRACK/SS pin is used
for power supply tracking and soft-start programming.
