PIN FUNCTIONS
(See Package Description for Pin Assignment)
V IN (Bank 1): Power Input Pins. Apply input voltage be-
tween these pins and PGND pins. Recommend placing
input decoupling capacitance directly between V IN pins
and PGND pins.
V OUT (Bank 3): Power Output Pins. Apply output load
between these pins and PGND pins. Recommend placing
output decoupling capacitance directly between these pins
and PGND pins. See Figure 17.
PGND (Bank 2): Power ground pins for both input and
output returns.
V OSNS– (Pin M12): (–) Input to the Remote Sense Ampli-
fier. This pin connects to the ground remote sense point.
The remote sense amplifier is used for V OUT ≤3.3V. Tie to
INTV CC if not used.
V OSNS+ (Pin J12): (+) Input to the Remote Sense Ampli-
fier. This pin connects to the output remote sense point.
The remote sense amplifier is used for V OUT ≤3.3V. Tie to
GND if not used.
DIFFV OUT (Pin K12): Output of the Remote Sense Ampli-
fier. This pin connects to the V OUT_LCL pin. Leave floating
if remote sense amplifier is not used.
DRV CC (Pin E12): This pin normally connects to INTV CC
for powering the internal MOSFET drivers. This pin can
be biased up to 6V from an external supply with about
50mA capability, or an external circuit shown in Figure 18.
This improves efficiency at the higher input voltages by
reducing power dissipation in the module.
INTV CC (Pin A7, D9): This pin is for additional decoupling
of the 5V internal regulator. These pins are internally con-
nected. Pin A7 is a test pin.
PLLIN (Pin A8): External Clock Synchronization Input to
the Phase Detector. This pin is internally terminated to
SGND with a 50k resistor. Apply a clock with high level
above 2V and below INTV CC . See Applications Information.
TRACK/SS (Pin A9): Output Voltage Tracking and Soft- Start
Pin. When the module is configured as a master output,
then a soft-start capacitor is placed on this pin to ground to
control the master ramp rate. A soft-start capacitor can be
used for soft-start turn on as a stand alone regulator. Slave
operation is performed by putting a resistor divider from
the master output to ground, and connecting the center
point of the divider to this pin. See Applications Information.
MPGM (Pins A12, B11): Programmable Margining Input.
A resistor from this pin to ground sets a current that is
equal to 1.18V/R. This current multiplied by 10kΩ will
equal a value in millivolts that is a percentage of the 0.6V
reference voltage. See Applications Information. To parallel
LTM4601AHVs, each requires an individual MPGM resistor.
Do not tie MPGM pins together. Both pins are internally
connected. Pin A12 is a test pin.
f SET (Pins B12, C11): Frequency Set Internally to 850kHz.
An external resistor can be placed from this pin to ground
to increase frequency. See Applications Information for
frequency adjustment. Both pins are internally connected.
Pin B12 is a test pin.
V FB (Pin F12): The Negative Input of the Error Amplifier.
Internally, this pin is connected to V OUT_LCL pin with a
60.4k precision resistor. Different output voltages can be
programmed with an additional resistor between V FB and
SGND pins. See Applications Information.
MARG0 (Pin C12): This pin is the LSB logic input for the
margining function. Together with the MARG1 pin it will
determine if margin high, margin low or no margin state
is applied. The pin has an internal pull-down resistor of
50k. See Applications Information.
MARG1 (Pin D12): This pin is the MSB logic input for the
margining function. Together with the MARG0 pin it will
determine if margin high, margin low or no margin state
is applied. The pin has an internal pull-down resistor of
50k. See Applications Information.
SGND (Pins H12, H11, G11): Signal Ground. These pins
connect to PGND at output capacitor point. See Figure 17.
