Feature Description
Remote On/Off
The Austin SuperLynx
an On/Off pin for remote On/Off operation of the module.
If not using the remote On/Off pin, leave the pin open
(module will be On). The On/Off pin signal (Von/Off) is
referenced to ground. To switch the module on and off
using remote On/Off, connect an open collector npn
transistor or N-channel FET between the On/Off pin and
the ground pin (See Figure 27).
During a logic-high (On/Off pin is pulled high internal to
the module) when the transistor is in the Off state, the
power module is ON. The maximum allowable leakage
current of the transistor when Von/off = V
During a logic-low when the transistor is turned-on, the
power module is OFF. During this state VOn/Off is less
than 0.3V and the maximum IOn/Off = 1mA.
Figure 27. Remote On/Off Implementation.
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.
The typical average output current during hiccup is 3A.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, module operation is disabled. The module will begin
to operate at an input voltage above the undervoltage
lockout turn-on threshold.
Overtemperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the thermal reference point T

Output Voltage Programming
The output voltage of the Austin SuperLynx
be programmed to any voltage from 0.75Vdc to 5.5Vdc
by connecting a resistor (shown as Rtrim in Figure 28)
between the Trim and GND pins of the module.
Without an external resistor between the Trim and
GND pins, the output of the module will be 0.7525Vdc.
To calculate the value of the trim resistor, Rtrim for a
desired output voltage, use the following equation:
Rtrim is the external resistor in Ω
Vo is the desired output voltage
For example, to program the output voltage of the Austin
SuperLynx
follows:

voltage using an external resistor.

applying a voltage between the TRIM and GND pins
(Figure 29). The following equation can be used to
determine the value of Vtrim needed to obtain a desired
output voltage Vo:
