Feature Description
Remote On/Off
The Austin MicroLynx
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 module on and off using
remote On/Off, connect an open collector pnp transistor
between the On/Off pin and the V
When the transistor Q1 is in the OFF state, the power
module is ON (Logic Low on the On/Off pin of the
module) and the maximum Von/off of the module is 0.4 V.
The maximum allowable leakage current of the transistor
when Von/off = 0.4V and V
logic-high when the transistor is in the active state, the
power module is OFF. During this state VOn/Off =10 -
14V and the maximum IOn/Off = 1mA.
Figure 27. Remote On/Off Implementation
Remote On/Off can also be implemented using open-
collector logic devices with an external pull-up resistor.
Figure 28a shows the circuit configuration using this
approach. Pull-up resistor, R
should be 68k (+/-5%) for proper operation of the module
over the entire temperature range.

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 2A.
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 over temperature protection in a fault
condition, the unit relies upon the thermal protection
feature of the controller IC. The unit will shutdown if the
thermal reference point T

as a guarantee that the unit will survive temperatures
beyond its rating. The module will automatically restarts
after it cools down.
