Feature Description
Remote On/Off
The Austin Lynx
On/Off pin for remote On/Off operation. 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 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 3 A.
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

the thermal shutdown is not intended as a guarantee that
the unit will survive temperatures beyond its rating. The
module will automatically restart after it cools down.
Output Voltage Programming
The output voltage adjustment feature allows the output
voltage set point to be increased or decreased by
connecting an external resistor between the TRIM pin
and Vo pin (decrease output voltage) or GND pin
(increase output voltage).
To trim up output voltage set point using an external
resistor, connect Rtrim-up between the TRIM and GND
pins (Figure 28). The value of Rtrim-up resistor is defined
as:
Rtrim-up is the external resistor in Ω
Vo,set is the nominal output voltage
Vo is the desired trim-up voltage
For example, to trim up the output voltage of the 1.5V
module (AXA010A0M93-SR) by 8% to 1.62V, Rtrim-up is
calculated as follows:
Vo,set = 1.5V
Vo = 1.62V:

output voltage using an external resistor.
To trim down output voltage set point using an external
resistor, connect Rtrim-down between TRIM and Vo pins
(Figure 29). The value of Rtrim-down resistor is defined
as:
