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
125
T
guarantee that the unit will survive temperatures
beyond its rating. Once the unit goes into thermal
shutdown it 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.
Output Voltage Programming
The output voltage of the 12V Mega TLynx
be programmed to any voltage from 0.8dc to
3.63Vdc by connecting a resistor (shown as R
Figure 31) between Trim and GND pins of the
module. Without an external resistor between Trim
and GND pins, the output of the module will be
0.8Vdc. To calculate the value of the trim resistor,
R
equation:
R
Vo is the desired output voltage
By using a ±0.5% tolerance trim resistor with a TC
of ±100ppm, a set point tolerance of ±1.5% can be
achieved as specified in the electrical specification.
Table 1 provides Rtrim values required for some
common output voltages. The POL Programming
Tool, available at
Design Tools section, helps determine the required
external trim resistor needed for a specific output
voltage.

Remote Sense
The 12V Mega TLynx
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 must not exceed 0.5V. Note that the
output voltage of the module cannot exceed the
specified maximum value. This includes the voltage
drop between the SENSE and Vout pins. When the
Remote Sense feature is not being used, connect
the SENSE pin to the VOUT pin.
Voltage Margining
Output voltage margining can be implemented in
the 12V Mega TLynx
resistor, R
pin for margining-up the output voltage and by
connecting a resistor, R
to output pin for margining-down. Figure 32 shows
the circuit configuration for output voltage
margining. The POL Programming Tool, available
at
section, also calculates the values of R
R
margin. Please consult your local Lineage Power
technical representative for additional details.

prebiased output as long as the prebias voltage is
0.5V less than the set output voltage. Note that
prebias operation is not supported when output
voltage sequencing is used.
