Feature Descriptions
Figure 23. Output ripple voltage for various output
voltages with external 2x10 µF, 2x47 µF, 4x47 µF or
8x47 µF ceramic capacitors at the output (50A load).
Input voltage is 12V.
Safety Considerations
For safety agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards,
i.e., UL 60950-1 2nd, CSA C22.2 No. 60950-1-07, DIN
EN 60950-1:2006 + A11 (VDE0805 Teil 1 + A11):2009-
11; EN 60950-1:2006 + A11:2009-03.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements. The power module
has extra-low voltage (ELV) outputs when all inputs are
ELV. The input to these units is to be provided with a
surface mount, fast acting fuse (ie. Littelfuse 456030
series) with a maximum rating of 30A in the positive input
lead.
Remote On/Off
The GigaTLynx
pin for remote On/Off operation. If not using the On/Off
pin, connect the pin to ground (the module will be ON).
The On/Off signal (V
circuit configuration for remote On/Off operation of the
module using the On/Off pin is shown in Figure 24.
During a Logic High on the On/Off pin (transistor Q1 is
OFF), the module remains OFF. The external resistor R1
should be chosen to maintain 3.0V minimum on the
On/Off pin to ensure that the module is OFF when
transistor Q1 is in the OFF state. Suitable values for R1
are 4.7K for input voltage of 12V and 3K for 5Vin. During
Logic-Low when Q1 is turned ON, the module is turned
ON.
The On/Off pin can also be used to synchronize the
output voltage start-up and shutdown of multiple modules
in parallel. By connecting On/Off pins of multiple

Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit should be 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 should operate
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 125
exceeded at the thermal reference point T
shutdown is not intended as a 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, module operation will be 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 GigaTLynx
programmable to any voltage from 0.7 Vdc to 2.0Vdc by
connecting a single resistor (shown as Rtrim in Figure 25)
between the TRIM+ and TRIM pins of the module. The
following equation will be used to set the output voltage of
the module:
