Feature Description
Remote On/Off
The Austin Lynx
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 29. Circuit configuration for using negative
logic 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 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
equipped with a thermal shutdown circuit. The unit will
shutdown if the thermal reference point T
125
intended as a guarantee that the unit will survive
temperatures beyond its rating. The module will
automatically restarts after it cools down.

SIP Non-isolated Power Modules, Programmable:
The output voltage of the Austin Lynx
programmed to any voltage from 0.75 Vdc to 3.3 Vdc by
connecting a single resistor (shown as Rtrim in Figure
31) 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 Lynx
follows:
Figure 31. Circuit configuration for programming
output voltage using an external resistor.
Table 1 provides Rtrim values for some common output
voltages
By using a 1% tolerance trim resistor, set point
tolerance of ±2% is achieved as specified in the
electrical specifications. The POL Programming Tool,
available at
Tools section, helps determine the required external
trim resistor needed for a specific output voltage
