LTM4611
pin FuncTions
PLLFLTR/f
for the Internal Phase Detector. LTM4611’s default switch-
ing frequency is 500kHz. Its switching frequency can be
increased by connecting a resistor from this pin to INTV
or decreased by connecting a resistor from this pin to
SGND. See the Applications Information section.
V
Internally, this pin is connected to V
precision resistor. Different output voltages can be pro-
grammed with an additional resistor between the V
GND pins. In PolyPhase
together allows for parallel operation. See the Applications
Information section for details.
TRACK/SS: (A9) Output Voltage Tracking Pin and Soft-
Start Inputs. The pin has a 1.4µA pull-up current source.
A capacitor from this pin to ground will set a soft-start
ramp rate. In tracking, the regulator output can be tracked
to a different voltage. The different voltage is applied to
a voltage divider then the slave output’s track pin. This
voltage divider is equal to the slave output’s feedback
divider for coincidental tracking. Tie all TRACK/SS pins
together for parallel operation. See the Applications In-
formation section.
COMP: (A11) Current Control Threshold and Error Amplifier
Compensation Point. The current comparator threshold
increases with this control voltage. Tie all COMP pins
together for parallel operation. The device is internally
compensated.
RUN: (A10) Run Control Pin. A voltage above 1.35V will
turn on in the module. The V
of the LTM4611 must be set with resistor networks from
V
pins together for parallel operation.
