DRV
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
16. This improves effi ciency at the higher input voltages
by reducing power dissipation in the modules.

TRACK/SS (Pin A9): Output Voltage Tracking and Soft-
Start Pin. When the module is confi gured 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 the ground,
and connecting the center point of the divider to this pin.
See Applications Information.
MPGM (Pin A12): Programmable Margining Input. A re-
sistor 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 refer-
ence voltage. See Applications Information. To parallel
LTM4603HVs, each requires an individual MPGM resistor.
Do not tie MPGM pins together.
