Feature Descriptions
Remote Enable
The 12V Pico TLynx
On/Off pin for remote On/Off operation. Two On/Off
logic options are available. In the Positive Logic
On/Off option, (device code suffix “4” – see Ordering
Information), the module turns ON during a logic High
on the On/Off pin and turns OFF during a logic Low.
With the Negative Logic On/Off option, (no device
code suffix, see Ordering Information), the module
turns OFF during logic High and ON during logic Low.
The On/Off signal is always referenced to ground. For
either On/Off logic option, leaving the On/Off pin
disconnected will turn the module ON when input
voltage is present.
For positive logic modules, the circuit configuration for
using the On/Off pin is shown in Figure 53.
Figure 53. Circuit configuration for using positive
On/Off logic.
For negative logic On/Off modules, the circuit
configuration is shown in Fig. 54.

On/Off logic.

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.
Overtemperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the overtemperature threshold of 140
exceeded at the thermal reference point T
thermal shutdown is not intended as a guarantee that
the unit will survive temperatures beyond its rating.
Once the unit goes into thermal shutdown it will then
wait to cool before attempting to restart.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module
will begin to operate at an input voltage above the
undervoltage lockout turn-on threshold.
Output Voltage Programming
The output voltage of the 12V Pico TLynx
modules can be programmed to any voltage from
0.6dc to 5.5Vdc by connecting a resistor between the
Trim and GND pins of the module. Certain restrictions
apply on the output voltage set point depending on the
input voltage. These are shown in the Output Voltage
vs. Input Voltage Set Point Area plot in Fig. 55. The
Lower Limit curve shows that for output voltages of
2.4V and higher, the input voltage needs to be larger
than the minimum of 3V.

Point Area plot showing limits where the output
voltage can be set for different input voltages.
Without an external resistor between Trim and GND
pins, the output of the module will be 0.6Vdc. To
