Feature Descriptions
Remote On/Off
Austin SuperLynx
feature an On/Off pin for remote On/Off operation.
Two On/Off logic options are available in the Austin
SuperLynx
signal, device code suffix “4”, turns the module ON
during a logic High on the On/Off pin and turns the
module OFF during a logic Low. Negative logic
On/Off signal, no device code suffix, turns the module
OFF during logic High and turns the module ON
during logic Low.
For positive logic modules, the circuit configuration for
using the On/Off pin is shown in Figure 27. The
On/Off pin is an open collector/drain logic input signal
(Von/Off) that is referenced to ground. During a logic-
high (On/Off pin is pulled high internal to the module)
when the transistor Q1 is in the Off state, the power
module is ON. Maximum allowable leakage current of
the transistor when Von/off = V
Applying a logic-low when the transistor Q1 is turned-
On, the power module is OFF. During this state
VOn/Off must be less than 0.3V. When not using
positive logic On/off pin, leave the pin unconnected or
tie to V
Figure 27. Circuit configuration for using positive
logic On/OFF.
For negative logic On/Off devices, the circuit
configuration is shown is Figure 28. The On/Off pin is
pulled high with an external pull-up resistor (typical
R
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 2.5 Vdc. 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.

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
exceeds 125
is not intended as a guarantee that the unit will
survive temperatures beyond its rating. The
module will automatically restarts after it cools
down.
