Feature Description
Remote On/Off
The Austin SuperLynx
On/Off pin for remote On/Off operation. The On/Off pin
is pulled high with an external pull-up resistor (typical
Rpull-up = 68k, ± 5%) as shown in Fig. 28. When
transistor Q1 is in the Off state, logic High is applied to
the On/Off pin and the power module is Off. The
minimum On/off voltage for logic High on the On/Off pin
is 1.5Vdc. To turn the module ON, logic Low is applied
to the On/Off pin by turning ON Q1. When not using the
negative logic On/Off, leave the pin unconnected or tie
to GND.
Figure 28. Circuit configuration for On/Off.
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 3.5A.
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
exceeds 125
not intended as a guarantee that the unit will survive
temperatures beyond its rating. The module will
automatically restarts after it cools down.

Output Voltage Programming
The output voltage of the Austin SuperLynx
be programmed to any voltage from 0.75 Vdc to 3.63
Vdc by connecting a single resistor (shown as Rtrim in
Figure 29) between the TRIM and GND pins of the
module. Without an external resistor between the TRIM
pin and the ground, the output voltage of the module is
0.7525 Vdc. To calculate the value of the resistor Rtrim
for a particular output voltage Vo, use the following
equation:
For example, to program the output voltage of the
Austin SuperLynx
calculated is follows:

voltage using an external resistor.

applying a voltage between the TRIM and GND pins
(Figure 30). The following equation can be used to
determine the value of Vtrim needed to obtain a desired
output voltage Vo:
