Feature Description
Remote On/Off
Austin SuperLynx
an On/Off pin for remote On/Off operation. Two On/Off
logic options are available in the Austin SuperLynx
series modules. Positive Logic On/Off 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
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
up
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

temperatures beyond its rating. The module will
