Pin Designation Function
1
SmartSync
This input pin sychronizes the switching
frequency of the module to external
clock frequency. The SmartSync feature
can be used to sychronize the switching
frequency of multipe PMP 5818UW P
modules, aiding EMI noise suppression
efforts. If unused, this pin should be
2
VI
The positive input voltage power node
to the module, which is referenced to
common GND.
3
GND
This is the common ground connection
for the VI and Vo power connections. It
is also the 0 Vdc reference for the control
4
GND
This is the common ground connection
for the VI and Vo power connections. It
is also the 0 Vdc reference for the control
5
Vo
The regulated positive power output
with respect to the GND.
6
+Sense
The sense input allows the regulation
circuit to compensate for voltage drop
between the module and the load. The
+Sense pin should always be connected
to V either at the load for optimal
7
-Sense
The sense input allows the regulation
circuit to compensate for voltage drop
between the module and the load. For
optimal voltage accuracy, -Sense must
be connectted to GND(pin 4) , very
8
Vo Adjust
A 0.05 W 1% resistor must be directly
connected between this pin and pin 7 (-
Sense) to set the output voltage to a
value higher than 0.69 V. The
temperature stability of the resistor
should be 100 ppm/℃ (or better). The
setpoint range for the output voltage is
from 0.69V to 5.5 V. If left open circuit,
the output voltage defaults to its lowest
value. For further information, on output

Turbo Trans This input pin adjusts the transient
response of the regulator. To activate
the Turbo TransTM feature, a 1%, 50mW
resistor must be connected between this
pin and pin 6 (+Sense) very close to the
module. For a given value of output
capacitance, a reduction in peak output
voltage deviation is achieved by using
this feature. If unused, this pin must be
left open circuit External capacitance
10
Track
This is an analog control input that
enables the output voltage to follow an
external voltage. This pin becomes active
typically 20 ms after the input voltage
has been applied, and allows direct
control of the output voltage from 0 V
up to the nominal set-point voltage.
Within the control voltage is raised
above this range, the module regulates
at its set-point voltage. The features
allows the output voltage to rise
simultaneously with other modules
powered from the same input bus. If
unused, this input should be connected
