Preliminary Data Sheet
February 1, 2011
Without an external resistor between Trim and GND
pins, the output of the module will be 0.6Vdc. To
calculate the value of the trim resistor, Rtrim for a
desired output voltage, should be as per the following
equation:
Rtrim is the external resistor in kΩ
Vo is the desired output voltage. Table 1 provides
Rtrim values required for some common output
voltages.
Remote Sense
The power module has a Remote Sense feature to
minimize the effects of distribution losses by regulating
the voltage at the SENSE pin. The voltage between
the SENSE pin and VOUT pin should not exceed 0.5V.
Voltage Margining
Output voltage margining can be implemented in the
module by connecting a resistor, R
Trim pin to the ground pin for margining-up the output
voltage and by connecting a resistor, R
the Trim pin to output pin for margining-down. Figure
43 shows the circuit configuration for output voltage
margining. The POL Programming Tool, available at
www.lineagepower.com
also calculates the values of R
for a specific output voltage and % margin. Please
consult your local Lineage Power technical
representative for additional details.

Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current limiting
continuously. At the point of current-limit inception, the
unit enters hiccup mode. The unit operates normally
once the output current is brought back into its
specified range.
Overtemperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the overtemperature threshold of 120(Q1) /
130(L1)
point T
will then wait to cool before attempting to restart.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module
will begin to operate at an input voltage above the
undervoltage lockout turn-on threshold.
